Ferroelectric RAM

(F-ram)

A type of memory that retains its contents after power is removed. Despite the name, FRAM contains no iron; the chips contain ceramic crystals that take on positive or negative polarity when hit with an electronic charge. FRAM is found mainly in consumer devices and, because of its low power requirements, could also be used in devices that only need to activate for brief periods (e.g., a subway pass that powers up as you pass through an electronic field, registers you passing through the gate, and then powers down).
