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.

Features
■ 128-Kbit ferroelectric random access memory (F-RAM) logically organized as 16K × 8
    ❐ High-endurance 100 trillion (1014) read/writes
