The U632H16 has two separate modes of o peration: SRAM mode and nonvolatile mode. In SRAM mode, the memory operates as an ordinary st atic RAM. In nonvolatile operation, data is transferred in parallel from SRAM to EEPROM or rom EEPROM to SRAM. In this mode SRAM functions are disabed.
The U632H16 is a fast s tatic RAM (25, 35, 45 ns), w ith a nonvolatile electr ically erasable PROM (EEPROM) element incorporated n each static memory cell. The SRAM can be read and wri tten an unlimited number of ti mes, while ndependent nonvolatile data resides in EEPROM. Data transfers rom the SRAM to the EEPROM (the STORE operation) take place automatically upon power down using charge stored in an external 100 µF capacitor. Transfers from he EEPROM to the SRAM (the RECALL operation) take place automatically on power up. The U632H16 combines the high performance and ease of use of a fast SRAM with nonvolatile data integrity.
