U631H256 Datasheet - Simtek

U631H256 SoftStore 32K x 8 nvSRAM

The U631H256 has two separate modes of operation: SRAM mode and nonvolatile mode. In SRAM mode, the memory operates as an ordinary static RAM. In nonvolatile operation, data is transferred in parallel from SRAM to EEPROM or from EEPROM to SRAM. In this mode SRAM functions are disabled. The U631H256 .
