DESCRIPTION

The Simtek STK14C88-3 is a fast static

RAM

with a

nonvolatile element incorporated in each static

memory cell. The

SRAM

can be read and written an

unlimited number of times, while independent, non-

volatile data resides in nonvolatile elements. Data

transfers from the

SRAM

to the nonvolatile elements

(the

STORE

operation) can take place automatically

on power down. A 68µF or larger capacitor tied from

CAP

to ground guarantees the

STORE

operation,

regardless of power-down slew rate or loss of power

from “hot swapping”. Transfers from the nonvolatile

elements to the

SRAM

(the

RECALL

operation) take

place automatically on restoration of power. Initia-

tion of

STORE

and

RECALL

cycles can also be soft-

ware controlled by entering specific read

sequences. A hardware

STORE

may be initiated with

the HSB pin.
