ABSTRACT:
The present invention provides a method of driving a nonvolatile flip-flop circuit comprising the following steps of: a data hold step of holding an input data signal D utilizing polarization of a ferroelectric material of a ferroelectric gate transistor (601) when the data signal D is input while a first clocked inverter (604), a second clocked inverter (603), and a third switching element (602) are turned on and a first switching element (605), a second switching element (607), and a third clocked inverter (608) are turned off; and a data output step of outputting an output signal Q (−Q) based on the held data signal D placing the first clocked inverter (604), the second clocked inverter (603), and the third switching element (602) in the OFF state and placing the first switching element (605), the second switching element (607), and the third clocked inverter (608) in the ON state so as to interrupt an input of a data signal and maintain a polarization state of the ferroelectric material of the ferroelectric gate transistor (601).
