DESCRIPTION
The Simtek STK25CA8 is a fast static RAM with a nonvolatile, electrically erasable PROM 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 the EEPROM. Data transfers from the SRAM to the EEPROM (the STORE operation) can take place automatically on power down using charge stored in system capacitance. Transfers from the EEPROM to the SRAM (the RECALL operation) take place automatically on restoration of power.

FEATURES
• Nonvolatile Storage without Battery Problems
• Directly Replaces 128K x 8 Static RAM, Battery Backed RAM or EEPROM
• 35ns and 45ns Access Times
• STORE to EEPROM Initiated by AutoStore™ on Power Down
• RECALL to SRAM on Power Restore
• 22mA ICC at 200ns Cycle Time
• Unlimited READ, WRITE and RECALL Cycles
• 1,000,000 STORE Cycles to EEPROM
• 100-Year Data Retention Over Full Commercial Temperature Range
• Commercial and Industrial Temperatures
• 32-Pin 600 mil Dual In-Line Module
