In the present application, a control end of a controllable switch is connected to a negative end of an output memristor in a MAGIC-based AND logic gate, and whether a second memristor is powered on is controlled by the controllable switch. Thus, when resistance value states of two input memristors in the AND logic gate are different, the controllable switch will conduct and power on the second memristor, and the second memristor will present a low-resistance state at this time.

An exclusive OR logic gate is formed by combining the two input memristors and the second memristor.
