Product Summary

The FM25256B-GTR is a 256-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or FRAM 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 EEPROM and other nonvolatile memories. These capabilities make the FM25256B-GTR ideal for nonvolatile memory applications requiring frequent or rapid writes or low power operation.
