Simtek U632H64
The U632H64 has two separate modes of operation: SRAM mode and nonvolatile mode. The U632H64 is a fast static RAM (25 ns), with a nonvolatile electrically erasable PROM (EEPROM) element incorporated in each static memory cell. The U632H64 combines the high performance and ease of use of a fast SRAM with nonvolatile data integrity.| Part No. | U632H64 |
