An F-RAM is nonvolatile and performs reads and writes similar to a RAM. It provides reliable data retention for 151 years while eliminating the plexities, overhead, and system-level reliability problems caused by serial flash, EEPROM, and other nonvolatile memories. Unlike serial flash and EEPROM, the FM25V01A performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after each byte is successfully transferred to the device. The next bus cycle can mence without the need for data polling. In addition, the product offers substantial write endurance pared with other nonvolatile memories. The FM25V01A is capable of supporting 1014 read/write cycles, or 100 million times more write cycles than EEPROM. These capabilities make the FM25V01A ideal for nonvolatile memory applications requiring frequent or...
