The Simtek STK12C68-M is a fast static RAM (40, 45
and 55ns), with a nonvolatile EEPROM element incor-
porated 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 transfers from the SRAM to the EEPROM (the
STORE operation) take place automatically upon power
down using charge stored in an external 100
μ
F
capacitor. Transfers from the EEPROM to the SRAM
(the RECALLoperation) take place automatically on
power up. Software sequences may also be used to
initiate both STOREand RECALLoperations. A
STOREcan also be initiated via a single pin.
The STK12C68-M is available in the following pack-
ages: a 28-pin 300 mil ceramic DIP and 28-pad LCC.
