ATTACHMENT TO NOTIFICATION OF LATE FILING (FORM 12b-25) FOR SIMTEK CORPORATION





PART III - NARRATIVE

The Registrant acquired certain assets from Zentrum Mikroelektronik Dresden AG
("ZMD") on December 30, 2005. Because the assets acquired did not represent a
complete business unit of ZMD, it took ZMD additional time to prepare historical
financial information related to the ZMD assets necessary to complete the Form
10-K. The auditors for the Registrant completed the required audit on March 30,
2006. The Registrant requires additional time to incorporate this information
into its Form 10-K.
