Item 1.01  Entry into a Material Definitive Agreement.

     On June 28, 2005, Simtek Corporation (the "Simtek"), along with Simtek's
wholly-owned subsidiary, Q-DOT, Inc., entered into a waiver letter (the
"Waiver") with Renaissance Capital Growth & Income Fund III, Inc., Renaissance
US Growth Investment Trust PLC, BFS US Special Opportunities Trust PLC
(collectively, the "RENN Capital Parties") with respect to the 7.50% Convertible
Debentures issued by Simtek to the RENN Capital Parties on June 28, 2002 in the
aggregate principal amount of $3,000,000 (the "Debentures").

     Under the Debentures, Simtek was obligated to begin making mandatory
principal redemption installments to the RENN Capital Parties on June 28, 2005
and every month thereafter in the amount of $10 per $1,000 of the then remaining
outstanding principal amount. As a result of the Waiver, however, the RENN
Capital Parties waived the requirement that Simtek begin making mandatory
principal redemption installments on June 28, 2005 (and monthly thereafter) and
instead agreed that Simtek will begin making such installments on July 1, 2006
and every month thereafter in the amount of $13.33 per $1,000 of the then
remaining outstanding principal amount.

     In exchange for the Waiver, Simtek issued to the RENN Capital Parties
warrants to purchase 200,000 shares of Simtek's common stock at $0.50 per share
with an exercise period of 5 years.

     A copy of Simtek's press release announcing the Waiver is included herewith
and attached as Exhibit 99.1. A copy of the Waiver is included herewith and
attached as Exhibit 99.2.
