The UT62L5128 is a 4,194,304-bit high speed CMOS static random access memory organized as 524,288 words by 8 bits. It is fabricated using high performance, high reliability CMOS technology. The UT62L5128 is designed for high speed system applications. It is particularly well suited for battery back-up nonvolatile memory applications. The UT62L5128 operates from a single 2.7V~3.6V power supply and all inputs and outputs are fully TTL compatible.
1. CMOS Low operating power
2. Single 2.7V~3.6V power supply
3. All inputs and outputs TTL compatible
4. Fully static operation
5. Three state outputs
6. Data retention voltage : 1.5V (min)
The Simtek STK10C68 is a fast static RAM(25, 30, 35, and 45ns), with a nonvolatile electrically-erasable PROM (EEPROM) element incorporated in each static memory cell. The SRAMcan be read and written an unlimited number of times, while independent nonvolatile data resides in EEPROM. Data may easily be transferred from the SRAMto the EEPROM (STORE), or from the EEPROMto the SRAM(RECALL) using the NE pin. It combines the high performance and ease of use of a fast SRAMwith nonvolatile data integrity.
1. 25, 30, 35 and 45ns Access Times
2. 12, 15, 20 and 25ns Output Enable Access
3. Unlimited Read and Write to SRAM
4. Hardware STORE Initiation
5. Automatic STORE Timing
