STK12C68 8K x 8 AutoStore™ nvSRAM QuantumTrap™ CMOS Nonvolatile Static RAM is a fast static RAM produced by Simtek. It has a non-volatile element that can be read and written an unlimited number of times, while independent, non-volatile data resides in Nonvolatile Elements.
The SIMTEK STK12C68 is a fast static RAM with a nonvolatile element incorporated in each memory cell. It supports unlimited read and write cycles while retaining independent nonvolatile data. The device features an 'AutoStore' function that automatically transfers SRAM data to nonvolatile elements upon power down, provided a capacitor of 68uF or larger is connected.
