DESCRIPTION
The Simtek STK10C68 is a fast static RAM with a nonvol-
atile 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
Non-
volatile Elements. Data may easily be transferred from
the SRAM to the
Nonvolatile Elements (the STORE oper-
ation
), or from the
Nonvolatile Elements to the SRAM
(the RECALL operation), using the NE pin.
Transfers
from the Nonvolatile Elements to the SRAM (the
RECALL
operation) also take place automatically on
restoration of power. The STK10C68 combines the high
performance and ease of use of a fast SRAM with nonvol-
atile data integrity.
The STK10C68 features industry-standard pinout for non-
volatile RAMs. MIL-STD-883 and Standard Military Draw-
ing (SMD #5962-93056) devices are available.
