Product Summary

The FM25V20-DG is a 2-megabit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 10 years while eliminating the complexities, overhead, and system level reliability problems caused by Serial Flash and other nonvolatile memories. Unlike Serial Flash, the FM25V20-DG performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after it has been transferred to the device. The next bus cycle may commence without the need for data polling.
