Item 1.01  Entry into a Material Definitive Agreement.

     On May 5, 2005, Simtek Corporation (the "Company") closed a Share Purchase
Agreement for a $4 million private placement of 6,740,816 shares of the
Company's common stock with Cypress Semiconductor Corporation ("Cypress") and a
Development and Production Agreement with Cypress to jointly develop a
0.13-micron Silicon-Oxide-Nitride-Oxide-Silicon (SONOS) nonvolatile memory
process. The Company and Cypress also entered into an Escrow Agreement pursuant
to which the Company deposited $3 million into an escrow account in order to
support and make certain payments for the 0.13-micron process and product
developments. Cypress also received a warrant to purchase 5,055,612 shares of
the Company's common stock at $0.7772 per share with a term of 10 years. The
Company has granted to Cypress certain registration rights with respect to the
shares issued under the Share Purchase Agreement and the shares issuable upon
exercise of the warrant. A copy of the press release announcing the transaction
is included herewith and attached as Exhibit 99.1. A copy of the Share Purchase
Agreement, the Development and Production Agreement, the Escrow Agreement, the
Stock Purchase Warrant and the Registration Rights Agreement entered into in
connection with the transaction are included herewith and attached as Exhibit

     On May 5, 2005, the Company sold 6,740,816 shares of the Company's common
stock to Cypress and issued a warrant to Cypress to purchase 5,055,612 shares of
the Company's common stock at $0.7772 per share with a term of 10 years. The
aggregate offering price for the common stock and the warrant in the transaction
was $4 million. The issuance of the common stock and the warrant are exempt from
registration pursuant to Rule 506 promulgated under, and Section 4(2) of, the
