  • Patent number: 11967953
    Abstract: A non-volatile Boolean logic circuit based on memristors and an operation method, which performs logic operations on the input logic value P and/or the input logic value Q. The logic circuit includes: a controller, a memristor M1, a memristor M2 and a resistor. The controller sets the memristor M2 to a high resistance state before performing the logic operation. When performing the logic operation, a voltage A is applied to the memristor M1, a voltage B is applied to the memristor M2, a voltage C is applied to the resistor. The resistance state of the memristor M2 is the result of the logic operation. When a logic operation is performed on the logic value P and the logic value Q or only on the logic value Q, the controller further sets the memristor M1 to the resistance state corresponding to the logic value Q before performing the logic operation.
