DESCRIPTION
The Simtek STK14C88-M is a fast static
RAM
with a
nonvolatile, electrically erasable
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) can take place auto-
matically on power down. A 68
μ
F or larger capacitor
tied from V
CAP
to ground guarantees the
STORE
operation, regardless of power-down slew rate or
loss of power from “hot swapping”. Transfers from
the
EEPROM
to the
SRAM
(the
RECALL
operation)
take place automatically on restoration of power. Ini-
tiation of
STORE
and
RECALL
cycles can also be
software
controlled
by
sequences. A hardware
STORE
may be initiated with
the HSB pin.
