Abstract: PURPOSE:To minimize voltage to be impressed to the insulating film of a capacitor, and to improve reliability by providing a means to control and set the potential of the electrode of one side of a memory capacitor at the time of the read-out of data and the means to set the potential of the capacitor electrode as it is prescribed at the time of rewrite-in after the read-out. CONSTITUTION:The electrode of one side of a memory capacitor CO keeps the voltage V1 at the time of memory 1', and keeps V2<V1 at the time of '0'. An address signal A is inputted and supply voltage Vcc is impressed to a decoder 10, and constant voltage VS and control signal phi1, phi2 are supplied to a voltage lowering part 20. At the time of the read-out, the electrode of one side of CO is set at V1>V3>V2 in the case of '1', and at V2 in the case of '0'. Usually, V4=(V1+V2)/2 is given to the electrode of the other side (l20 side) of CO, and at the time of the rewrite-in after the read-out, V5=V4-(V1-V3) is given to the electrode of the other side while the electrode of one side being fixed at a former value, and when CO is '0', the electrode of the other side is floated, and the electrode of the other side is returned to V4 again, and the electrode of one side of '1' is set at V1 from V3 by capacity coupling. As the result, potential difference to be impressed to the insulating film of CO becomes (V1-V2)/2 at its maximum value, and the improvement of the reliability of CO and the saving of power consumption can be realized.
