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 EEPROM and other nonvolatile memories. Unlike EEPROM, the FM24V02A 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. F-RAM also exhibits much lower power during writes than EEPROM because write operations do not require an internally elevated power supply voltage for write circuits. The FM24V02A is capable of supporting 1014 read/write cycles, or 100 million times more write cycles than EEPROM. These capabilities make the FM24V02A ideal for nonvolatile...
