A ferroelectric random access memory or FRAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 45 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. The FM24C64 performs write operations at bus speed. No write delays are incurred. Data is written to the memory array in the cycle after it has been successfully transferred to the device. The next bus cycle may commence immediately. The FM24C64 is capable of supporting 10 12 read/write cycles, or a million times more write cycles than EEPROM. These capabilities make the FM24C64 ideal for nonvolatile memory applications requiring frequent or rapid writes. Examples range from data collection where the number of write cycles may be critical, to demanding industrial controls where the long write time of EEPROM can cause data loss. The combination of features allows more frequent data writes with less overhead for the system. The FM24C64 provides substantial benefits to users of serial EEPROM, yet these benefits are available in a hardware drop-in replacement. The FM24C64 is available in an industry standard 8-pin SOIC package using a two-wire protocol. The specifications are guaranteed over an industrial temperature range of -40°C to +85°C.
