U634H256XS
PowerStore 32K x 8 nvSRAM Die

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 U634H256XS 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.
