ABSTRACT:
Non-volatile latch circuit10of the present invention comprises ferroelectric capacitor1provided with a first electrode1a, second electrode1b, and ferroelectric film1cthat lies between these electrodes; reset terminal Tre that is connected to first electrode1aand a CMOS inverter element2that is connected to second electrode1bof ferroelectric capacitor1; voltage switching terminal Tpl that applies a voltage to second electrode1b; switching element5that is connected between second electrode1band second input terminal Tpl and switches a voltage applied to second electrode1b; and set terminal Tse that applies a voltage for switching on or off switching element5, wherein the voltage generated in second electrode1bcaused by polarization retained by ferroelectric film1cis higher than the threshold voltage Vtn of NMISFET4of CMOS inverter element2.
