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 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 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
sequences. A hardware
STORE
may be initiated with
the HSB pin.
