The FM3116-S is a 16-kilobit (2K x 8) 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 complexities, overhead, and system level reliability problems caused by EEPROM, Flash and other nonvolatile memories.
