Item 1.01.  Entry into a Material Definitive Agreement.

On May 4, 2005, Simtek Corporation (the "Company") accelerated the vesting of
certain unvested and out-of-the money non-qualified stock options with an
exercise price per share greater than $0.62. Options to purchase approximately
1.7 million shares of the Company's common stock are now exercisable. All other
terms and conditions applicable to outstanding stock option grants, including
the exercise prices and number of shares subject to the accelerated options,
were unchanged. The stock option agreements with respect to the accelerated
options will be amended accordingly. Options held by non-employee directors were
excluded from the vesting acceleration. A copy of the Company's press release
announcing the acceleration of certain stock options is included herewith and
attached as Exhibit 99.1.

Under the recently revised Financial Accounting Standards Board Statement No.
123, "Share-Based Payment," the Company will apply the expense recognition
provisions relating to stock options beginning in the first quarter of 2006. As
a result of the acceleration, the Company expects to reduce the stock option
expense it otherwise would be required to record by approximately $506,000 in
2006, $215,000 in 2007, and $14,000 in 2008 on a pre-tax basis.
