The invention provides a memristor-based cubic root logic circuit. The memristor-based cubic root logic circuit comprises six input ends S1-S6 and two output ends Y2 and Y1. The input ends S3, S4 andS5 are connected with the intermediate output end R1 through a memristor-based first channel circuit; the input ends S1-S6 are connected with the intermediate output end R2 through a memristor-based second channel circuit, and the input ends S1-S6 are connected with the intermediate output end R3 through a memristor-based third channel circuit; the input end S6 and the intermediate output ends R1,R2 and R3 are connected with the output end Y1 through a memristor-based fourth channel circuit, and the input ends S4, S5 and S6 are connected with the output end Y2 through a memristor-based fifthchannel circuit. The six-input cubic root logic circuit has high accuracy and sensitivity, a theoretical basis is provided for designing more complex large-scale logic circuit operation operation, anddevelopment of an artificial intelligence computer is promoted.

Description

technical field [0001] The invention relates to the technical field of logic circuits, in particular to a memristor-based cube root logic circuit. Background technique [0002] Memristor is a non-linear resistor with memory function, which is the fourth basic circuit element besides resistors, capacitors and inductors. Due to its basic position in circuit theory and its important prospects in computer information storage, massive data processing, artificial neural networks, and new switch models, memristors have become research hotspots at home and abroad. [0003] At present, information processors have higher and higher requirements for low power consumption, high density and fast response, and need to change the current transistor-based computing structure. In order to solve the problems of CMOS logic size reduction and leakage current, non-volatile memory devices are developing towards high-efficiency non-volatile logic devices. Among these new logic schemes, memristor...
