Additional preview pages of the U632H64 datasheet.

The U632H64 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 ns Access Time 12 ns Output Enable Access Time ICC = 15 mA at 200 ns Cycle Time Automatic STORE to EEPROM on Power Down using external capacitor Hardware or Software initiated STORE (STORE Cycle Time < 10 ms) Automatic STORE Timing 105 STORE cycles to EEPROM 10 years data retention in EEPROM Automatic RECALL on Power Up Software RECALL Initiation (RECALL Cycle Time < 20 μs) Unlimited RECALL cycles from EEPROM .
