com U635H16 PowerStore 2K x 8 nvSRAM Features Description The U635H16 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 U635H16 is a fast static RAM (25, 35, 45 ns), with a nonvolatile 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 resides in EEPROM.
Data transfers from the SRAM to the EEPROM (the STORE operation) take place automatically upon power down using charge stored in system capacitance.
Transfers from the EEPROM to the SRAM (the RECALL operation) take place automatically on power up.
The U635H16 combines the high performance and ease of use of a fast SRAM wi...
