Functional Description

The FM25V01A is a 128-Kbit nonvolatile memory employing an advanced ferroelectric process. 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.
