General Description

The FM22L16 is a 256Kx16 nonvolatile memory that reads and writes like a standard SRAM.

A ferroelectric random access memory or FRAM is nonvolatile, which means that data is retained after power is removed.

It provides data retention for over 10 years while eliminating the reliability concerns, functional disadvantages, and system design plexities of battery-backed SRAM (BBSRAM).

Key Features

  • 4Mbit Ferroelectric Nonvolatile RAM.
  • Organized as 256Kx16.
  • Configurable as 512Kx8 Using /UB, /LB.
