Abstract:
1. A method of operating a non-volatile logic circuit, the method comprising: a step (a) of preparing the non-volatile logic circuit, wherein: a step (b) of configuring one logic in the nonvolatile logic circuit, the one logic being selected from logical conjunction (AND), logical disjunction (OR), logical non-conjunction (NAND), logical non-disjunction (NOR), and logical exclusive disjunction (XOR), wherein: when the logical disjunction (OR) is configured, the voltages which satisfy the following inequality (II) are applied, when the logical non-conjunction (NAND) is configured, the voltages which satisfy the following inequality (III) are applied, when the logical non-disjunction (NOR) is configured, the voltages which satisfy the following inequality (IV) are applied, when the logical exclusive disjunction (XOR) is configured, the voltages which satisfy the following inequality (V) are applied, a step (c) of writing one state selected from the group consisting of first to fourth states into the non-volatile logic circuit, wherein: when the second state is written, voltages which satisfy the following inequality (VII) are applied, when the third state is written, voltages which satisfy the following inequality (VIII) are applied, when the fourth state is written, voltages which satisfy the following inequality (IX) are applied, a step (d) of measuring current generated by applying a potential difference between the power electrode and the output electrode to determine whether the semiconductor layer between the power electrode and the output electrode is a high resistance state or a low resistance state on the basis of the current.
