ABSTRACT:
The unit cell is constructed to have a volatile memory element provided with a capacitor element adapted to store and sustain an electric charge only in a state in which electric power is supplied, and a nonvolatile memory element adapted to save said electric charge stored in said capacitor element when the supply of said electric power is cut off. One end of said capacitor element is connected by way of said nonvolatile memory element to a potential supply line. Said nonvolatile memory element acts as a conductive element in a state in which said electric power is supplied and acts as a cut-off element in a state in which said electric power is not supplied, and in addition, has a threshold that varies in a case where the electric charge stored in said capacitor element corresponds to a predetermined potential level.
