Low Voltage Powerstore 32k X 8 Nvsram

The UL634H256 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 disab- LED The UL634H256 is a fast static RAM (35 and 45 ns), with a nonvo- latile electrically erasable PROM (EEPROM) element incorporated in each static memory cell. The SRAM CAN be read and written an unlimited number of times, while independent nonvolatile data resi- des in EEPROM Data transfers from the SRAM to the EEPROM (the STORE opera- tion) take place automatically upon power down using charge stored in an external 68 F capacitor. Trans- fers from the EEPROM to the SRAM (the RECALL operation) take place automatically on power up. The UL634H256 combines the high performance and ease of use of a fast SRAM with nonvolatile data integrity. By Unkown
