Abstract:
1. A method of operating a non-volatile logic circuit, comprising: a step (a) of preparing the non-volatile logic circuit, wherein: the non-volatile logic circuit comprises a control electrode, a ferroelectric layer, a semiconductor layer, and an electrode group, the control electrode, the ferroelectric layer, the semiconductor layer, and the electrode group are stacked in this order, the electrode group comprises a electric current power electrode, an output electrode, a first input electrode, and a second input electrode, X direction, Y-direction, and Z-direction denote a longitudinal direction of the ferroelectric layer, a direction orthogonal to the longitudinal direction, and a stacking direction, respectively, the first input electrode and the second input electrode are interposed between the electric current power electrode and the output electrode along the X-direction, and the first input electrode is next to the second input electrode along the Y-direction; a step (b) of writing one state selected from the group consisting of first, second, third, and fourth states into the non-volatile logic circuit, wherein: a step (c) of measuring current generated by applying a voltage between the electric current power electrode and the output electrode to determine on the basis of the current which of the high or low resistant state the non-volatile logic circuit has.
