8-pin small outline integrated circuit (SOIC) package

FRAM (Ferroelectric RAM)

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.
