Description

The Simtek STK14CA8 is a fast static RAM with a  nonvolatile element in each memory cell. The  embedded nonvolatile elements incorporate  Simtek's QuantumTrapTM  technology producing the  world's most reliable nonvolatile memory. The  SRAM provides unlimited read and write cycles,  while independent, nonvolatile data resides in the  highly reliable  QuantumTrapTM cell. Data transfers  from the SRAM to the nonvolatile elements (the  STORE operation) takes place automatically at  power down. On power up, data is restored to the  SRAM (the RECALL operation) from the nonvolatile  memory. Both the STORE and RECALL operations  are also available under software control.
