Functional Overview
The FM25V20A is a 2-Mbit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes similar to a RAM. It provides reliable data retention for 121 years while eliminating the complexities, overhead, and system level reliability problems caused by serial flash, EEPROM, and other nonvolatile memories.
