FM24C04B Overview
The FM24C04B is a 4-Kbit 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 151 years while eliminating the plexities, overhead, and system-level reliability problems caused by EEPROM and other nonvolatile memories.
