DESCRIPTION
The STK25C48 is a fast SRAM with a nonvolatile 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 the
Nonvolatile
Elements. Data transfers from the SRAM to the Nonvola-
tile Elements (the STORE operation) can take place auto-
matically on power down using charge stored in system
capacitance. Transfers from the
Nonvolatile Elements to
the SRAM (the RECALL operation) take place automati-
cally on restoration of power. The nvSRAM can be used in
place of existing 2K x 8 SRAMs and also matches the
pinout of 2K x 8 battery-backed SRAMs, EPROMs and
EEPROM
s, allowing direct substitution while enhancing
performance. No support circuitry is required for micro-
processor interfacing.
