22C10 256-BitNonvolatileCMOSStaticRAM

The CAT22C10 NVRAM is a 256-bit nonvolatile memory organized as 64 words x 4 bits. The high speed Static RAM array is bit for bit backed up by a nonvolatile E2PROM array which allows for easy transfer of data from RAM array to E2PROM (STORE) and from E2PROM to RAM (RECALL). STORE operations are comp.
