FM25040A Datasheet 4kb Fram Serial Memory

Manufacturer: Ramtron International

Overview: .. .. FM25040A 4Kb FRAM Serial Memory.

General Description

The FM25040A is a 4-kilobit nonvolatile memory employing an advanced ferroelectric process.

A ferroelectric random access memory or FRAM is nonvolatile but operates in other respects as a RAM.

It provides reliable data retention for 45 years while eliminating the plexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories.
