PROBLEM TO BE SOLVED: To provide a nonvolatile sequential circuit or the like which can hold the data despite the cut-off of its power supply. SOLUTION: At an inverter circuit part INV1, a pair of transistors(TR) constructing a conventional CMOS inverter are replaced with the TR NT and PT of MFMIS structures. A ferroelectric layer 32 of the TR NT holds a polarization state corresponding to an ON state and the layer 32 of the TR PT holds a polarization state corresponding to an OFF state respectively even when the power supply of a semiconductor device is cut. When the power supply is applied again, both TR NT and PT are turned on and off respectively according to the polarization states held by each layer 32. Thus, the part INV1 is reset in a state that is held before the power supply is cut when the power supply is applied again. |
