Additional preview pages of the U635H64 datasheet.

The U635H64 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.

High-performance CMOS nonvolatile static RAM 8192 x 8 bits 25, 35 and 45 ns Access Times 12, 20 and 25 ns Output Enable Access Times ICC = 15 mA at 200 ns Cycle Time Automatic STORE to EEPROM on Power Down using system capacitance Software initiated STORE (STORE Cycle Time < 10 ms) Automatic STORE Timing 105 STORE cycles to EEPROM 10 ye.
