Capstore 32k X 8 Nvsram

The U637256 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 U637256 is a static RAM with a nonvolatile electrically erasable PROM (EEPROM) element incor- porated 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 operation) take place automatically upon power down using charge stored in an integraed capacitor. Transfers from the EEPROM to the SRAM (the RECALL operation) take place automatically on power up. The U637256 combines the ease of use of an SRAM with nonvolatile data integrity. By Unkown
