STK11C68

8K x 8 nvSRAM

QuantumTrap™ CMOS

Nonvolatile Static RAM

FEATURES

DESCRIPTION

• 20ns, 25ns, 35ns and 45ns Access Times

The Simtek STK11C68 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), or from EEPROM to

SRAM (the RECALL operation), take place using a

software sequence. Transfers from the EEPROM to

the SRAM (the RECALL operation) also take place

automatically on restoration of power.

• STORE to EEPROM Initiated by Software

• RECALL to SRAM Initiated by Software or

Power Restore

• 10mA Typical I_CCat 200ns Cycle Time

• Unlimited READ, WRITE and RECALL Cycles

• 1,000,000 STORE Cycles to EEPROM

• 100-Year Data Retention over Full Industrial

Temperature Range

• Commercial and Industrial Temperatures

• 28-Pin DIP and SOIC Packages

The STK11C68 is pin-compatible with industry-

standard SRAMs. MIL-STD-883 device is also

available (STK11C68-M).
