Description
The FM25L04B is a 4-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories.
