DESCRIPTION

The Simtek STK10C68 is a fast static

RAM

with a nonvol-

atile 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

Non-

volatile Elements

. Data may easily be transferred from

the

SRAM

to the

Nonvolatile Elements

(the

STORE

oper-

ation

), or from the

Nonvolatile Elements

to the

SRAM

(the

RECALL

operation), using the NE pin.

Transfers

from the Nonvolatile Elements to the

SRAM

(the

RECALL

operation) also take place automatically on

restoration of power.

The STK10C68 combines the high

performance and ease of use of a fast

SRAM

with nonvol-

atile data integrity.

The STK10C68 features industry-standard pinout for non-

volatile

RAM

s. MIL-STD-883 and Standard Military Draw-

ing (

SMD

#5962-93056) devices are available.
