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 complexities, overhead, and system-level reliability problems caused by serial flash, EEPROM, and other nonvolatile memories.
Unlike serial flash and EEPROM, the FM25V02A 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 commence without the need for data polling.
In addition, the product offers substantial write endurance compared with other nonvolatile memories.
The FM25V02A is capable of supporting 1014 read/write cycles, or 1...
