Obsolete - Not Recommended for New Designs com U630H16XS HardStore 2K x 8 nvSRAM Die Features Description The U630H16 has two separate modes of operation: SRAM mode and non-volatile mode, determined by the state of the NE pad.
In SRAM mode, the memory operates as an ordinary static RAM.
In non-volatile operation, data is transferred in parallel from SRAM to EEPROM or from EEPROM to SRAM.
In this mode SRAM functions are disabled.
The U630H16 is a fast static RAM (25, 35, 45 ns), with a non-volatile 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 non-volatile ...
