DESCRIPTION

The Simtek STK16CA8 is a fast static RAM with a nonvolatile element in each static 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 nonvolatile elements. Data transfers from the SRAM to the nonvolatile elements (the STORE operation) can take place automatically on power down or under software control. An internal capacitor guarantees the STORE operation, even under extreme power-down slew rates or loss of power from “hot swapping”.
