[SIMTEK]

DESCRIPTION

The Simtek STK14CA8 is a fast static RAM with a nonvolatile element in each memory cell. The embedded nonvolatile elements incorporate Simtek’s QuantumTrap? 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 QuantumTrap? 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.
