DESCRIPTION

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

SRAM

(the

RECALL

operation), take place using a

software sequence. Transfers from the

EEPROM

the

SRAM

(the

RECALL

operation) also take place

automatically on restoration of power.

The STK11C68 is pin-compatible with industry-

standard

SRAM

s. MIL-STD-883 device is also

available (STK11C68-M).
