摘　　要：Memristors are a promising solution for building an advanced computing system due to their excellent characteristics,including small energy consumption,high integration density,fast write/read speed,great endurance and so on.In this work,we firstly design three basis logic XNOR1,XNOR2 and XOR gates by virtue of memristor ratioed logic(MRL),and further construct 1-bit numerical comparators,2-bit numerical comparators and full adder 1 based on the above XNOR1,XNOR2 and XOR gates.Furthermore,we propose and design a universal logic circuit that can realize four different kinds of logic functions(AND,OR,XOR,XNOR)at the same time.Subsequently,a full adder 2 is built using XOR function of this universal logic circuit.Compared with the traditional CMOS circuits,the universal logic circuit designed in this work exhibits several merits such as fewer components,less power,and lower delay.This work demonstrates that memristors can be used as a potential solution for building a novel computing architecture.
