Serial SRAM is a low-power, volatile memory product. Again, although it is a volatile memory, it has a battery-backed feature that allows it to replace non-volatile memory. In addition, its low pin count offers easy integration into smaller devices. onsemi 8-pin TSSOP  Serial SRAM provides a far simpler solution compared to 40-pin TSSOP Parallel SRAM. Serial SRAM provides unlimited write cycles unlike EEPROM and Flash. In addition, it has a higher voltage compatibility, and very low operating and standby power. Therefore, it often replaces an EEPROM or Flash in applications which need data persistence and unlimited re-write capabilities.
