DESCRIPTION

The Simtek STK11C88-3 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), or from Nonvolatile Elements

SRAM

(the

RECALL

operation) are initiated using a

software sequence. Data transfers from the Nonvol-

atile Elements to the

SRAM

(the

RECALL

operation)

also occur upon restoration of power.
