STATEMENT PURSUANT TO RULE 429(b) Pursuant to Rule 429 under the Securities Act, this post-effective amendment also relates to an aggregate of 9,615,384 shares of common stock previously registered but not sold under the registration statement on Form SB-2 (File No. 333-104854) (the "Additional Registration Statement"), which has been declared effective by the Commission. This post-effective amendment constitutes both (i) post-effective amendment no. 5 to this registration statement (File No. 333-111408), and (ii) post-effective amendment no. 8 to the Additional Registration Statement. Deregistration of Securities This Post-Effective Amendment No. 5 relates to: (i) the Registration Statement on Form SB-2 (File No. 333-111408) (the "Registration Statement") of Simtek Corporation (the "Registrant"), which registered for resale from time to time by certain selling security holders up to 12,017,367 shares of common stock of the Registrant, including up to 10,365,384 shares of the Registrant's common stock issuable upon the exercise of certain warrants or the conversion of certain debentures; and (ii) the Registration Statement on Form SB-2 (File No. 333-104854) (the "Additional Registration Statement") of the Registrant which registered for resale from time to time by certain selling security holders up to 9,615,384 shares of common stock of the Registrant issuable upon the conversion of certain debentures, all of which were included in post-effective amendment no. 4 to the Registration Statement. The selling security holders of the Registrant are named in the Registration Statement and the Additional Registration Statement. The Registration Statement and the Additional Registration Statement were declared effective by the Securities and Exchange Commission on December 29, 2003 and May 8, 2003, respectively. Since the Registrant is no longer a "small business issuer", the Registrant has determined that it should file a registration statement on Form S-2 (rather than Form SB-2) with respect to the resale of the 12,017,367 shares of common stock of the Registrant. With this Post-Effective Amendment No. 5 to the Registration Statement, the Registrant hereby deregisters all of the unsold shares of common stock covered by the Registration Statement and the Additional Registration Statement.
