DESCRIPTION
The Simtek STK12C68 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
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 specific read
sequences. A hardware
STORE
may be initiated with
the HSB pin.
