Abstract

PURPOSE: To read out the signal to the bistable circuit consisting of MOS transistor, by applying the signal voltage to the junction point of two binary capacitors and by memorizing the information of bistable circuit in non-volatile manner as the threshold value of the capacitance change of the both capacitors.
