                                     SUMMARY

     THIS SUMMARY HIGHLIGHTS SELECTED INFORMATION FROM THIS PROSPECTUS AND DOES
NOT CONTAIN ALL OF THE INFORMATION THAT MAY BE IMPORTANT TO YOU. PLEASE
CAREFULLY READ THE ENTIRE PROSPECTUS AND THE DOCUMENTS INCORPORATED BY
REFERENCE.

OUR COMPANY

     We develop, market and subcontract the production of nonvolatile
semiconductor memories. Nonvolatility prevents loss of programs and data when
electrical power is removed from the semiconductor. Our memory products feature
fast data access and programming speeds. Our products are targeted for use in
commercial or military electronic equipment markets. These markets are
industrial control systems, office automation, medical instrumentation,
telecommunication systems, cable television, and numerous military systems,
including communications, radar, sonar and smart weapons. Our wholly owned
subsidiary, Q-DOT Group, Inc., specializes in advanced technology research and
development for data acquisition, signal processing, imaging and data
communications.

     Our principal executive office is located at 4250 Buckingham Dr. #100;
Colorado Springs, Colorado 80907. Our telephone number is 719-531-9444.

THE OFFERING

     We are registering 8,126,936 shares of our common stock that may be offered
for resale by SF Capital Partners Ltd., Bluegrass Growth Fund LP, Bluegrass
Growth Fund LTD and Merriman Curhan Ford & Co. We refer to these companies as
the "selling security holders."

     On October 12, 2004, we received $2,500,000 from SF Capital Partners Ltd.,
Bluegrass Growth Fund LP and Bluegrass Growth Fund LTD in return for issuing
5,159,959 shares of our common stock and warrants to acquire 2,579,980 shares of
our common stock. In connection with the $2,500,000 equity financing, we issued
to Merriman Curhan Ford & Co. warrants to acquire 386,997 shares of our common
stock. The warrants issued to the selling security holders have 5-year terms
with an exercise price of $0.627 per share.

                                  RISK FACTORS

     YOU SHOULD CONSIDER CAREFULLY THE FOLLOWING RISK FACTORS, AS WELL AS THE
OTHER INFORMATION IN THIS PROSPECTUS BEFORE BUYING OUR SHARES. THE SEMICONDUCTOR
INDUSTRY IS CHANGING RAPIDLY. THEREFORE, THE FORWARD-LOOKING STATEMENTS AND
STATEMENTS OF EXPECTATIONS, PLANS AND INTENT IN THIS PROSPECTUS ARE SUBJECT TO A
GREATER DEGREE OF RISK THAN SIMILAR STATEMENTS REGARDING SOME OTHER INDUSTRIES.

OUR LIMITED OPERATING CAPITAL AND OUR ABILITY TO RAISE ADDITIONAL MONEY MAY HARM
OUR ABILITY TO DEVELOP AND MARKET OUR PRODUCTS

     To date, we have required significant capital for product development,
subcontracted production and marketing. We have funded these from the sale of
products, the sale of product and technology licenses and from royalties as well
as from the sale of our convertible debt and equity securities.

     We have not seen any significant increase in our product sales in the past
year and our gross margins are less than we had anticipated. Therefore, our cash
requirements for the development, subcontracted production and marketing of our
existing product families have been difficult to maintain. We are not sure
whether we will be able to achieve an increase in product sales and gross
margins. We may need more capital in the next year and after that to develop new
products. We are not sure that we will be able to raise more capital on
reasonable terms, if at all. If we cannot, then we may not be able to develop
and market new products. The development, subcontracted production and marketing
of our existing products may also suffer, causing our financial position and
stock price to deteriorate.

WE MAY EXPERIENCE OPERATING LOSSES IN THE NEXT SEVERAL YEARS

     We began business in 1987. Through December 31, 2004, we had accumulated
losses of approximately $40.0 million. We realized net income for the first time
for the year ended December 31, 1997 and continued to realize net income through
June 30, 2000. Subsequent to June 30, 2000 and through December 31, 2004, we
realized net losses primarily as a result of accounting charges from the
purchase of incomplete research and development in September 2000, decreased
revenue, decreased gross margins and increased research and development costs
related to new product development. We may continue to experience net operating
losses for the foreseeable future. Continuing net operating losses could
materially harm our results of operations, increase our need for additional
capital in the future, and hurt our stock price.

WE MIGHT NOT BE ABLE TO RE-GAIN COMPLIANCE WITH CERTAIN COVENANTS SET FORTH IN
OUR LOAN AGREEMENT WITH RENN CAPITAL GROUP; IF WE ARE UNABLE TO DO SO, RENN
CAPITAL GROUP COULD ACCELERATE THE $3 MILLION LOAN AND FORECLOSE ON THE
COLLATERAL THAT WE GRANTED TO IT

     Our loan agreement with RENN Capital Group (formerly Renaissance Capital
Group, Inc.) contains various financial covenants. As of December 31, 2004, we
were not in compliance with two of the covenants set forth in the loan agreement
which covenants relate to the interest coverage ratio and debt to equity ratio.
On March 16, 2005, we received a waiver for the two covenants through January 1,
2006. However, significant variances in future actual operations from our
current estimates could result in the reclassification of this note to a current
liability. If the note becomes due and we cannot pay it, RENN Capital Group may
foreclose on the assets that we pledged as security for the note. This would
significantly harm our business.

BECAUSE OUR COMMON STOCK IS LISTED ONLY ON THE OTC ELECTRONIC BULLETIN BOARD, IT
WILL BE MORE DIFFICULT TO SELL OUR COMMON STOCK

     Our common stock is listed on the OTC Electronic Bulletin Board under the
symbol "SRAM." Our common stock was listed on the Nasdaq Small-Cap Market until
July 18, 1995, but, because we no longer met Nasdaq's listing requirements, our
common stock transferred to the OTC Electronic Bulletin Board as mandated by
Nasdaq rules. We may not be able to meet the requirements for relisting our
common stock on Nasdaq in the near future or in the longer term.




                                       4



     Securities that are not listed on the Nasdaq Small-Cap Market are subject
to a Securities and Exchange Commission rule that imposes special requirements
on broker-dealers who sell those securities to persons other than their
established customers and accredited investors. The broker-dealer must determine
that the security is suitable for the purchaser and must obtain the purchaser's
written consent prior to the sale. These requirements may make it more difficult
for our security holders to sell their securities and may affect our ability to
raise more capital. It may also make it harder for you to sell our stock than
the stock of some other companies.

IF WE CANNOT RECEIVE SILICON WAFERS WE REQUIRE TO MANUFACTURE OUR PRODUCTS FROM
CHARTERED SEMICONDUCTOR MANUFACTURING AT THE VOLUMES OR THE PRICES WE REQUIRE,
OUR REVENUES, EARNINGS AND STOCK PRICE COULD SUFFER

     We currently purchase the silicon wafers we require to build our 16
kilobit, 64 kilobit, 5 volt 256 kilobit and 3 volt 256 kilobit memory products
from Chartered Semiconductor Manufacturing Plc. of Singapore, or Chartered. We
have not had a manufacturing contract with Chartered since 1998. However, we
have maintained a good relationship with Chartered for the pricing and delivery
of our wafers. Due to our not having a contract with Chartered and the
volatility of the semiconductor market, we may have no control over the pricing
and availability of the wafers we require in order to build our products. The
risk of not receiving the products and pricing we need from Chartered has
escalated, but we are evaluating alternative sources of supply. We believe we
may have an alternative source for our 3 volt 256 kilobit memory product.
However, we cannot assure you that we will secure this or any alternative
source. In addition, we do not have an alternative source for our 16 kilobit, 64
kilobit and 5 volt 256 kilobit memory products at this time. If we are unable to
obtain the products and pricing we need, our business could suffer.

SINCE WE DEPEND GREATLY ON SUBCONTRACTORS, THEIR POOR PERFORMANCE COULD HURT OUR
OPERATIONS

     We subcontract the silicon wafer processing, product assembly, and product
testing portions of our business to independent companies. Our operating results
depend on these subcontractors' ability to supply us with silicon wafers that
meet our specifications and to assemble and test enough of our products to meet
our customers' needs.

     We have depended on Chartered to manufacture all of our silicon wafers for
our 0.8-micron memory products which accounted for approximately 86% of our
total revenue for 2004. These wafers are the raw materials required to
manufacture our semiconductor products. Without these wafers, we would be unable
to sell our products. If Chartered is unable to meet our silicon wafer needs on
time and at a price that we find acceptable, we would have to find another wafer
manufacturer. If we cannot find other suppliers, manufacturers or assemblers on
acceptable terms, we may not be profitable. In addition, our subcontractors must
be audited and recertified by us on a regular basis for us to continue to
produce military-qualified products. We cannot assure you that we will be able
to complete this recertification successfully or in a timely manner.

THE UNCERTAINTY INVOLVED IN MANUFACTURING SEMICONDUCTORS MAY INCREASE THE COSTS
AND DECREASE THE PRODUCTION OF OUR PRODUCTS

     In order for us to be profitable, we must keep our manufacturing costs down
and secure the production of sufficient product. Semiconductor manufacturing
depends on many factors that are very complex and beyond our control and often
beyond the control of our subcontractors. These factors include contaminates in
the manufacturing environment, impurities in the raw materials used and
equipment malfunctions. Under our arrangements with our subcontractors, our
subcontractors pass on to us substantially all of their costs that are unique to
the manufacture of our products. Accordingly, these factors could increase the
cost of manufacturing our products and decrease our profits. These factors could
also reduce the number of semiconductors that our subcontractors are able to
make in a production run. If our subcontractors produce fewer of our products,
our revenues may decline.

DELAYS IN MANUFACTURING MAY NEGATIVELY IMPACT OUR REVENUE AND NET INCOME

     It takes approximately three months for us to manufacture our
semiconductors. Any delays in receiving silicon wafers from our subcontractors
will delay our ability to deliver our products to customers. This would delay



                                       5



sales revenue and could cause our customers to cancel existing orders or not
place future orders. In addition, if we are not able to make all of our planned
semiconductors in a production run this could delay delivery of our products.
These delays could occur at any time and would affect our net income.

WE DEPEND ON INDEPENDENT SALES REPRESENTATIVES AND DISTRIBUTORS TO SELL OUR
PRODUCTS AND THE TERMINATION OF ANY OF THESE RELATIONSHIPS MAY HARM OUR REVENUE

     We use independent sales representatives and distributors to sell the
majority of our products. The agreements with these sales representatives and
distributors can be terminated without cause by either party with only 30 to 90
days written notice. If one or more of our sales representatives or distributors
terminates our relationship, we may not be able to find replacement sales
representatives and distributors on acceptable terms or at all. This would
affect our profitability. In addition, during 2004 approximately 35% of our
product sales were to three distributors. We are not sure that we will be able
to maintain our relationship with these distributors.

DELAYS IN OR FAILURE OF PRODUCT QUALIFICATION MAY HARM OUR BUSINESS

     Prior to selling a product, we must establish that it meets expected
performance and reliability standards. As part of this testing process, known as
product qualification, we subject representative samples of products to a
variety of tests to ensure that performance in accordance with commercial,
industrial and military specifications, as applicable. If we are unable to
successfully accomplish product qualification for our future products, we will
be unable to sell these future products. Even with successful initial product
qualifications, we cannot be assured that we will be able to maintain product
qualification or achieve sufficient sales to meet our operating requirements.

SINCE THE SEMICONDUCTOR INDUSTRY IS FAST CHANGING, OUR SUCCESS DEPENDS ON OUR
ABILITY TO INTRODUCE NEW PRODUCTS

     The semiconductor industry is characterized by rapid changes in technology
and product obsolescence. Our success in the semiconductor industry depends in
part upon our ability to expand our existing product families and to develop and
market new products. The technology we currently use may be made obsolete by
other competing or newly developed memory or other technologies. The development
of new semiconductor designs and technologies typically requires substantial
costs for research and development. Even if we are able to develop new products,
the success of each new product depends on several factors including whether we
selected the proper product and our ability to introduce it at the right time,
whether the product is able to achieve acceptable production yields and whether
the market accepts the new product. We cannot guarantee you that we will be
successful in developing new products or whether any products that we do develop
will satisfy the above factors. In September 2003, we began shipping samples of
our 1 megabit 3 volt nonvolatile semiconductor memory product. We cannot assure
you that we will not discover technical problems or manufacturing concerns with
this new product, that demand will develop for the new product or that we will
be able to sell this new product at a profit.

THE CYCLICALITY OF THE SEMICONDUCTOR INDUSTRY MAY PREVENT US FROM MAINTAINING A
CONSISTENT REVENUE STREAM AND MAY HARM OUR STOCK PRICE

     The semiconductor industry has historically experienced significant peaks
and valleys in sales volumes resulting in large variations of revenues and
resulting profits or losses. We do not have direct influence on the nature of
the broad semiconductor market. Variations in the revenues and profits within
the semiconductor industry may cause us significant losses in the future. If the
stock prices of many semiconductor companies decrease, our stock price may also
suffer. Recently, the semiconductor industry has experienced increased losses
and the stock prices of many semiconductor companies, including us, have
fluctuated.

OUR AGREEMENT WITH DONGBUANAM SEMICONDUCTOR TO CO-DEVELOP A SEMICONDUCTOR
PROCESS MODULE THAT COMBINES OUR NONVOLATILE TECHNOLOGY WITH ITS ADVANCED 0.25
MICRON DIGITAL COMPLEMENTARY METAL-OXIDE SEMICONDUCTOR FABRICATION WILL RESULT
IN SIGNIFICANT EXPENDITURES

     We entered into an agreement with Amkor Technology to cooperate to develop
a semiconductor process module that combines our nonvolatile technology with
Amkor's advanced 0.25 micron digital complementary metal-oxide semiconductor, or



                                       6



"CMOS," fabrication line. The module incorporates silicon oxide nitride oxide
silicon technology, which will be used to manufacture both high density silicon
oxide nitride oxide silicon flash and nonvolatile Static Random Access memories,
for stand alone and embedded products. Through 2004, our research and
development team along with Amkor's research and development team worked
aggressively on the co-development program. The co-development program is
scheduled to yield a qualified 1 megabit 3.0 volt nonvolatile Static Random
Access memory as the primary development vehicle. In February 2003, Amkor
Technology sold a controlling interest of its wafer fabrication facility to
DongbuAnam Semiconductor. All contractual obligations were transferred to Anam
U.S.A., a wholly-owned subsidiary of DongbuAnam Semiconductor. Our
co-development program has not been affected by the change in ownership and we
do not expect any material changes in the support required to complete the
program. There could, however, be changes made by the newly combined management
team that could postpone or cancel this co-development project.

     Since entering into the agreement with DongbuAnam Semiconductor we estimate
that we have spent approximately $5,300,000 in development costs. These costs
include increases in headcount, contract engineering services, equipment leases,
maintenance agreements for software and wafer fabrication costs. If DongbuAnam
Semiconductor terminates our agreement there is no guarantee that we could find
a suitable replacement. If we cannot find a replacement, a significant delay and
cost increase in the introduction of new products could result.

IF WE CANNOT REDUCE OUR MANUFACTURING COSTS RELATED TO OUR NEW 1 MEGABIT MEMORY
PRODUCT FAMILY, OUR REVENUES, EARNINGS AND STOCK PRICE COULD SUFFER

     During 2004, we began receiving silicon wafers from DongbuAnam
Semiconductor. The silicon wafers received from DongbuAnam Semiconductor are
used to manufacture our new 1 megabit product family. Currently, the
manufacturing yields we are achieving from these silicon wafers do not meet the
requirements we need in order to attain a cost effective solution. Our
engineering department, along with DongbuAnam's engineering department, is
focusing on increasing this manufacturing yield.

     Through 2004, the manufacturing cost related to the testing of our
1-megabit memory product family has been far greater than is economically
acceptable to be cost-effective in volume production. Our engineering department
is developing test programs intended to reduce our test cost. If we cannot
reduce this cost or improve our manufacturing yields on our 1-megabit memory
product family our gross margins could suffer.

THE INTENSE COMPETITION IN THE SEMICONDUCTOR INDUSTRY MAY CAUSE US TO LOSE SALES
REVENUE TO OTHER SUPPLIERS

     There is intense competition in the semiconductor industry. We experience
competition from a number of domestic and foreign companies, most of which have
significantly greater financial, technical, manufacturing and marketing
resources than we have. Our competitors include major corporations with
worldwide silicon wafer fabrication facilities and circuit production facilities
and diverse, established product lines. We also compete with emerging companies,
such as Ramtron International Corporation, attempting to obtain a share of the
market for our product families. If any of our new products achieve market
acceptance, other companies may sell competitive products at prices below ours.
This would have an adverse effect on our operating results. We have sold product
and technology licenses to Zentrum Mikroelektronik Dresden. We have granted this
company unlimited rights to much of our technology through its license
agreements with us. Zentrum Mikroelektronik Dresden has entered the market and
has become one of our significant competitors

GIVEN THE SCARCITY OF TRAINED PERSONNEL IN THE SEMICONDUCTOR INDUSTRY, THE LOSS
OF KEY EMPLOYEES COULD MATERIALLY AFFECT OUR FINANCIAL RESULTS

     Our success depends in large part on our ability to attract and retain
qualified technical and management personnel. There are limited personnel
trained in the semiconductor industry resulting in intense competition for these
personnel. If we lose any of our key personnel, this could have a material
adverse affect on our ability to conduct our business and on our financial
results.



                                       7



OUR PATENTS MAY NOT PROVIDE US EFFECTIVE INTELLECTUAL PROPERTY PROTECTION; THIS
COULD HARM OUR BUSINESS

     We have been issued 30 U.S. patents relating to specific aspects of our
current products. We have also applied outside the United States for patents on
our technology. We are not sure that any of the patents for which we have
applied will be issued or, even if they are issued, will provide us with
meaningful protection from competition. We may also not have the money required
to maintain or enforce our patent rights. Notwithstanding our patents, other
companies may obtain patents similar or relating to our patents.

     We seek to protect a significant portion of our intellectual property as
trade secrets, rather than patents. Unlike patents, trade secrets must remain
confidential in order to retain protection as proprietary intellectual property.
We cannot assure you that our trade secrets will remain confidential. If we lose
trade secret protection, our business could suffer.

IF OUR PRODUCTS AND TECHNOLOGY INFRINGE ON THIRD PARTY PATENTS, OUR PRODUCT
SALES MAY SUFFER

     We have not determined whether our products are free from infringement of
others' patents. If patent infringement claims are asserted against us and are
upheld, we will try to modify our products so that they are non-infringing. If
we are unable to do so, we will have to obtain a license to sell those products
or stop selling the products for which the claims are asserted. We may not be
able to obtain the required licenses. Any successful infringement claim against
us, our failure to obtain any required license or requirement for us to stop
selling any of our products, may force us to discontinue production and shipment
of these products. This may result in reduced product sales and harm our
revenues.

     In 1998, we received notice of a claim for an unspecified amount from a
foundation that owns approximately 180 patents and 70 pending applications. The
foundation claimed that some of the machines and processes used in the building
of our semiconductor devices infringe on the foundation's patents. In April
1999, we reached an agreement with the foundation for us to purchase a
nonexclusive license of the foundation's patents, based on our product offerings
and sales forecast at that time. If our products or actual sales revenue vary
significantly from the time of the agreement, we may be subject to additional
payments.

     In late 2002, we received notice of possible patent infringement from a
corporation that has acquired a portfolio of patents. We have reviewed the claim
and believe there are no potential infringements. As of December 31, 2004 we
have received no further notification from this corporation. If there are any
infringements, we believe we will be able to enter into a licensing agreement
with such company without any material impact on us.

FOREIGN CURRENCY EXCHANGE RATE FLUCTUATIONS MAY INCREASE OUR COSTS, LOWER OUR
REVENUES AND CAUSE LOSS OF CUSTOMERS TO OUR COMPETITORS

     We purchase materials, including silicon wafers, from outside the United
States. In 2004, over 62% of our sales were to customers located outside of the
United States. We operate using United States dollars as the functional
currency. Changes in foreign currency exchange rates can reduce our revenues and
increase our costs. For example, our subcontractors may increase the prices they
charge us, on a per purchase order basis, for silicon wafers if the United
States dollar weakens. Any large exchange rate fluctuation could affect our
ability to compete with manufacturers who operate using foreign currencies. We
do not try to reduce our exposure to these exchange rate risks by using hedging
transactions. Although we have not had any material losses due to exchange rate
fluctuations over the last three years, we cannot assure you that we will not
incur significant losses in the future.

IF WE ISSUE SECURITIES AT LOW PRICES IN THE FUTURE, SOME OF OUR SECURITY HOLDERS
MAY BE ENTITLED TO ACQUIRE MORE OF OUR SECURITIES, WHICH MAY DILUTE AND HARM THE
HOLDERS OF OUR COMMON STOCK

     We may be obligated under agreements with certain of our security holders
to issue to them additional securities in exchange for little or no
consideration if we sell our securities in the future at or below certain
prices. The issuance of such securities could dilute and harm the holders of our
common stock.



                                       8



BECAUSE WE DO NOT INTEND TO PAY DIVIDENDS IN THE FORESEEABLE FUTURE, YOUR
INVESTMENT RETURN MAY BE LIMITED

     We have never paid cash dividends on our common stock. We do not expect to
pay dividends in the foreseeable future. We intend to use any earnings to
finance growth. You should not expect to receive dividends on your shares of
common stock.

IF OUR BOARD OF DIRECTORS AUTHORIZES THE ISSUANCE OF PREFERRED STOCK, HOLDERS OF
OUR COMMON STOCK COULD BE DILUTED AND HARMED

     Our board of directors has the authority to issue up to 2,000,000 shares of
preferred stock in one or more series and to establish the preferred stock's
voting powers, preferences and other rights and qualifications without any
further vote or action by the shareholders. The issuance of preferred stock by
our board of directors could dilute and harm the rights of the holders of our
common stock. It could potentially be used to discourage attempts by others to
obtain control of us through merger, tender offer, proxy contest or otherwise by
making such attempts more difficult to achieve or more costly. Given our present
capital requirements, it is possible that we may need to raise capital through
the sale of preferred stock in the future.


                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus contains some "forward-looking statements" as defined in
the Private Securities Litigation Reform Act of 1995 and information relating to
us that are based on the beliefs of our management, as well as assumptions made
by and the information currently available to our management. When used in this
prospectus, the words "estimate," "project," "believe," "anticipate," "intend,"
"expect" and similar expressions are intended to identify forward-looking
statements. These statements reflect our current views with respect to future
events and are subject to risks and uncertainties that could cause actual
results to differ materially from those contemplated in these forward-looking
statements, including those risks discussed in this prospectus.

     You are cautioned not to place undue reliance on these forward-looking
statements, which speak only as of the date of this prospectus. Except for
special circumstances in which a duty to update arises when prior disclosure
becomes materially misleading in light of subsequent circumstances, we do not
intend to update any of these forward-looking statements to reflect events or
circumstances after the date of this prospectus or to reflect the occurrence of
unanticipated events.


                                 USE OF PROCEEDS

     8,126,936 shares are covered by this prospectus. These shares include
shares of our common stock issuable upon exercise of warrants issued to the
selling security holders incident to our October 12, 2004 equity financing. We
will not receive any proceeds from the resale of these shares by the selling
security holders. The selling security holders will receive all of the proceeds
from the sale of these shares. We will receive the proceeds from the exercise of
the warrants by the selling security holders, if any are exercised.

* Less than 1%

     On October 12, 2004, we closed a $2,500,000 equity financing with SF
Capital Partners Ltd., Bluegrass Growth Fund LP and Bluegrass Growth Fund LTD.
In exchange for the $2,500,000, we issued 4,127,967 shares of our common stock
to SF Capital Partners Ltd., 515,996 shares of our common stock to Bluegrass
Growth Fund LP and 515,996 shares of our common stock to Bluegrass Growth Fund
LTD. The purchase price was based on a 15% discount to the closing price of our
common stock as reported on the Over-the-Counter Bulletin Board on October 11,
2004, resulting in a price of $0.4845 per share. In addition to the shares of
common stock, SF Capital Partners Ltd., Bluegrass Growth Fund LP and Bluegrass
Growth Fund LTD received warrants to acquire 2,063,984, 257,998, and 257,998
shares of our common stock, respectively. The warrants have a 5-year term with
an exercise price of $0.627 per share. Merriman Curhan Ford & Co., the placement
agent for the $2,500,000 equity financing, received a cash payment of $187,500
and warrants to acquire 386,997 shares of our common stock. The warrants have a
5-year term with an exercise price of $0.627 per share. In addition, Merriman
Curhan Ford & Co. is entitled to receive another cash payment equal to 7.5% of
the capital received by us upon the exercise of the warrants issued to SF
Capital Partners Ltd., Bluegrass Growth Fund LP and Bluegrass Growth Fund LTD
pursuant to the $2,500,000 equity financing (provided such exercise is within an
applicable tail period).

                            DESCRIPTION OF SECURITIES

     Our amended and restated articles of incorporation and bylaws provide for a
classified board of directors when we have six or more directors. This may have
the effect of delaying or preventing changes in control of our management, which
could adversely affect the market price of our common stock by discouraging or
preventing takeover attempts that might result in the payment of a premium price
to our shareholders.

Common Stock

     We are authorized to issue 300,000,000 shares of common stock, par value
$0.01 per share. Each share of common stock entitles the holder thereof to one
vote on all matters submitted to a vote of the shareholders. Holders of common
stock do not have preemptive rights or rights to convert their common stock into
other securities. Holders of common stock are entitled to receive ratably such
dividends as may be declared by the board of directors out of funds legally
available therefor. In the event of our liquidation, dissolution or winding up,
holders of the common stock have the right to a ratable portion of the assets
remaining after payment of liabilities. Part of the common stock offered in this
prospectus is issuable to the selling securityholders under warrants to purchase
2,966,977 shares of common stock. The warrants have a 5-year term with an
exercise price of $0.627 per share. The exercise price of the warrants issued to
SF Capital Partners Ltd., Bluegrass Growth Fund LP and Bluegrass Growth Fund LTD
covering 2,579,980 shares of common stock may be adjusted in the event of a
stock split, stock combination, payment of dividends, a merger, a sale of all or
substantially all of the assets, a tender offer or exchange offer. In addition,
until approximately October 12, 2005, the exercise price of the warrants issued
to SF Capital Partners Ltd., Bluegrass Growth Fund LP and Bluegrass Growth Fund
LTD may be adjusted upon certain issuances by us of our common stock at less
than $0.627 per share. The exercise price of the warrants issued to Merriman
Curhan Ford & Co. covering 386,997 shares of common stock may be adjusted in the
event of a stock split, stock combination or payment of dividends.

Preferred Stock

     Our amended and restated articles of incorporation authorize 2,000,000
shares of $1.00 par value preferred stock. The board of directors has the
authority to issue preferred stock in one or more series and to fix the rights,
preferences, privileges and restrictions thereof, including dividend rights,
dividend rates, conversion rights, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares constituting
any series and the designation of such series, without further vote or action by
the shareholders. The issuance of preferred stock may have the effect of
delaying, deferring or preventing a change in control of us without further
action by the shareholders and may adversely affect the voting power and other
rights of the holders of common stock, including the loss of voting control to
others. As of the date of this prospectus, there are no shares of preferred
stock outstanding.



                              PLAN OF DISTRIBUTION

     The selling security holders and any of their pledgees, donees,
transferees, assignees and successors-in-interest may, from time to time, sell
any or all of their shares of common stock on any stock exchange, market or
trading facility on which the shares are traded or in private transactions.
These sales may be at fixed or negotiated prices. The selling security holders
may use any one or more of the following methods when selling shares:

o    ordinary brokerage transactions and transactions in which the broker-dealer
     solicits investors;

o    block trades in which the broker-dealer will attempt to sell the shares as
     agent but may position and resell a portion of the block as principal to
     facilitate the transaction;

o    purchases by a broker-dealer as principal and resale by the broker-dealer
     for its account;

o    an exchange distribution in accordance with the rules of the applicable
     exchange;



                                       11




o    privately negotiated transactions;

o    to cover short sales made after the date that this registration statement
     is declared effective by the Securities and Exchange Commission;

o    broker-dealers may agree with the selling security holders to sell a
     specified number of such shares at a stipulated price per share;

o    a combination of any such methods of sale; and

o    any other method permitted pursuant to applicable law.

     The selling security holders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

     Broker-dealers engaged by the selling security holders may arrange for
other brokers-dealers to participate in sales. Broker-dealers may receive
commissions or discounts from the selling security holders (or, if any
broker-dealer acts as agent for the purchaser of shares, from the purchaser) in
amounts to be negotiated. The selling security holders do not expect these
commissions and discounts to exceed what is customary in the types of
transactions involved.

     The selling security holders may from time to time pledge or grant a
security interest in some or all of the shares owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell shares of common stock from time to time under this
prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or
other applicable provision of the Securities Act of 1933 amending the list of
selling security holders to include the pledgee, transferee or other successors
in interest as selling security holders under this prospectus.

     Upon us being notified in writing by a selling security holder that any
material arrangement has been entered into with a broker-dealer for the sale of
common stock through a block trade, special offering, exchange distribution or
secondary distribution or a purchase by a broker or dealer, a supplement to this
prospectus will be filed, if required, pursuant to Rule 424(b) under the
Securities Act, disclosing (i) the name of each such selling security holder and
of the participating broker-dealer(s), (ii) the number of shares involved, (iii)
the price at which such the shares of common stock were sold, (iv)the
commissions paid or discounts or concessions allowed to such broker-dealer(s),
where applicable, (v) that such broker-dealer(s) did not conduct any
investigation to verify the information set out or incorporated by reference in
this prospectus, and (vi) other facts material to the transaction. In addition,
upon us being notified in writing by a selling security holder that a donee or
pledgee intends to sell more than 500 shares of common stock, a supplement to
this prospectus will be filed if then required in accordance with applicable
securities law.

     The selling security holders also may transfer the shares of common stock
in other circumstances, in which case the transferees, pledgees or other
successors in interest will be the selling beneficial owners for purposes of
this prospectus.

     The selling security holders and any broker-dealers or agents that are
involved in selling the shares may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales. In such event, any
commissions received by such broker-dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act. Discounts, concessions,
commissions and similar selling expenses, if any, that can be attributed to the
sale of securities will be paid by the selling security holders and/or the
purchasers. Each selling security holder has represented and warranted to us
that it acquired the securities subject to this registration statement in the
ordinary course of such selling security holder's business and, at the time of
its purchase of such securities such selling security holder had no agreements
or understandings, directly or indirectly, with any person to distribute any
such securities.



                                       12



     We have advised each selling security holder that it may not use shares
registered on this registration statement to cover short sales of common stock
made prior to the date on which this registration statement shall have been
declared effective by the Securities and Exchange Commission. If a selling
security holder uses this prospectus for any sale of the common stock, it will
be subject to the prospectus delivery requirements of the Securities Act. The
selling security holders will be responsible to comply with the applicable
provisions of the Securities Act of 1933 and the Securities Exchange Act of
1934, and the rules and regulations thereunder promulgated, including, without
limitation, Regulation M, as applicable to such selling security holders in
connection with resales of their respective shares under this registration
statement.

     We are required to pay all fees and expenses incident to the registration
of the shares, but we will not receive any proceeds from the sale of the common
stock. We have agreed to indemnify the selling security holders against certain
losses, claims, damages and liabilities, including liabilities under the
Securities Act. If the selling security holders use this prospectus for any sale
of the common stock, they will be subject to the prospectus delivery
requirements of the Securities Act.


                                  LEGAL MATTERS

     The validity of the shares offered hereby will be passed upon by Holme

     The above expenses will be borne by us.

ITEM 15.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

     The Colorado Business Corporation Act provides that a corporation may
indemnify a person made a party to a proceeding because the person is or was a
director against liability incurred in the proceeding if (a) the person
conducted himself or herself in good faith, (b) the person reasonably believed
(1) in the case of conduct in an official capacity with the corporation, that
his or her conduct was in the corporation's best interests; and (2) in all other
cases, that his or her conduct was at least not opposed to the corporation's
best interests and (c) in the case of any criminal proceeding, the person had no
reasonable cause to believe his or her conduct was unlawful. Such
indemnification is permitted in connection with a proceeding by or in the right
of the corporation only to the extent of reasonable expenses incurred in
connection with the proceeding. A corporation may not indemnify a director (a)
in connection with a proceeding by or in the right of the corporation in which
the director was adjudged liable to the corporation; or (b) in connection with
any other proceeding charging that the director derived an improper personal
benefit, whether or not involving action in an official capacity, in which
proceeding the director was adjudged liable on the basis that he or she derived
an improper personal benefit. The Colorado Business Corporation Act further
provides that a corporation, unless limited by its articles of incorporation,
shall indemnify a person who was wholly successful, on the merits or otherwise,
in the defense of any proceeding to which the person was a party because the
person is or was a director or officer, against reasonable expenses incurred by
him or her in connection with the proceeding.

     Our amended and restated articles of incorporation contain a provision that
requires us to indemnify, to the fullest extent permitted under law, directors
and officers against all costs and expenses reasonably incurred in connection
with the defense of any claim, action, suit or proceeding, whether civil,
criminal, administrative, investigative or other, in which such person may be
involved by virtue of being or having been a director, officer or employee.
Insofar as indemnification for liabilities arising under the Securities Act of
1933, as amended (the "Act"), may be permitted to directors, officers and
controlling persons of Simtek pursuant to the foregoing provisions, or
otherwise, Simtek has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable.

ITEM 17.  UNDERTAKINGS

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

     The undersigned registrant hereby undertakes to:

     (1)  To file, during any period in which offers or sales are being made, a
          post-effective amendment to this registration statement:

          (i)  To include any prospectus required by section 10(a)(3) of the
               Securities Act of 1933;

          (ii) To reflect in the prospectus any facts or events arising after
               the effective date of the registration statement (or the most
               recent post-effective amendment thereof) which, individually or
               in the aggregate, represent a fundamental change in the
               information in the registration statement. Notwithstanding the
               foregoing, any increase or decrease in volume of securities
               offered (if the total dollar value of securities offered would
               not exceed that which was registered) and any deviation from the
               low or high end of the estimated maximum offering range may be
               reflected in the form of prospectus filed with the Commission
               pursuant to Rule 424(b) (17 C.F.R.ss.230.424(b)) if, in the
               aggregate, the changes in volume and price represent no more than
               a 20% change in the maximum aggregate offering price set forth in
               the "Calculation of Registration Fee" table in the effective
               registration statement

         (iii) To include any material information with respect to the plan of
               distribution not previously disclosed in the registration
               statement or any material change to such information in the
               registration statement.

     (2)  That, for the purpose of determining any liability under the
          Securities Act of 1933, each such post-effective amendment shall be
          deemed to be a new registration statement relating to the securities
          offered therein, and the offering of such securities at that time
          shall be deemed to be the initial bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
          of the securities being registered which remain unsold at the
          termination of the offering.

     The undersigned registrant hereby undertakes to, for determining any
liability under the Securities Act, treat each post-effective amendment that
contains a form of prospectus as a new registration statement for the securities
offered in the registration statement, and that offering of the securities at
that time as the initial bona fide offering of those securities.
