The FM24C04A is a 4-kilobit nonvolatile memoryemploying an advanced ferroelectric process. Aferroelectric random access memory or FRAM isnonvolatile and performs reads and writes like aRAM. It provides reliable data retention for 10 yearswhile eliminating the complexities, overhead, andsystem level reliability problems caused by EEPROMand other nonvolatile memories.Unlike serial EEPROMs, the FM24C04A performswrite operations at bus speed. No write delays areincurred. Data is written to the memory array in thecycle after it has been successfully transferred to thedevice. The next bus cycle may commenceimmediately.
