Ferroelectric Random Access Memory (F-RAM) is energy-efficient and it has the highest-reliability of the non-volatile RAMs for both serial and parallel interfaces. Parts with suffix A are designed for automotive applications and are AEC-Q100 qualified.

Nonvolatile Ferroelectric RAM Memory

FRAM (Ferroelectric Random Access Memory) is a non-volatile memory that uses ferroelectric film as a capacitor for storing data. Possessing characteristics of both ROM and RAM devices, F-RAM features high-speed access, high endurance in write mode, low power consumption, non-volatility, and excellent tamper resistance. It is therefore Ideal memory for use in smart cards which need high security and low power consumption, as well as cellular phones and other devices.
