FEATURES

DESCRIPTION

• 25ns, 35ns and 45ns Access Times

• STORE to Nonvolatile Elements Initiated by

Hardware

• RECALL to SRAM Initiated by Hardware or

Power Restore

• Automatic STORE Timing

• 10mA Typical I_CCat 200ns Cycle Time

• Unlimited READ, WRITE and RECALL Cycles

• 1,000,000 STORE Cycles to Nonvolatile Ele-

ments

• 100-Year Data Retention over Full Industrial

Temperature Range

• Commercial and Industrial Temperatures

The Simtek STK20C04 is a fast static RAM with a non-

volatile element incorporated in each static memory

cell. The SRAM can be read and written an unlimited

number of times, while independent nonvolatile data

resides in nonvolatile elements. Data may easily be

transferred from the SRAM to the Nonvolatile Elements

(the STORE operation), or from the Nonvolatile Ele-

ments to the SRAM (the RECALL operation), using the

NE pin. Transfers from the Nonvolatile Elements to the

SRAM (the RECALL operation) also take place auto-

matically on restoration of power. The STK20C04

combines the high performance and ease of use of a

fast SRAM with nonvolatile data integrity.

The STK20C04 features industry-standard pinout for

nonvolatile RAMs in a 28-pin 600 mil plastic DIP.
