DESCRIPTION
The Simtek STK11C88-3 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
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.
