DESCRIPTION
The Simtek STK20C04 is a fast static
RAM
(30, 35,
45ns), with a nonvolatile electrically-erasable
PROM
(
EEPROM
) 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 may easily be transferred
from the
SRAM
to the
EEPROM
(
STORE
), or from the
EEPROM
to the
SRAM
(
RECALL
) using the NE pin. It
combines the high performance and ease of use of a
fast
SRAM
with nonvolatile data integrity.
The STK20C04 features the industry standard pinout
for nonvolatile
RAM
s in a 28-pin 600 mil plastic DIP.
