Two kinds of novel hybrid memristor-CMOS XOR gates and full adder circuits

Abstract

In this paper, we proposed two kinds of novel XOR gate circuits by using two memristors and four CMOS transistors. The architecture with two positive terminal of memristor connecting realizes AND and XOR logic simultaneously, while the other architecture with the negative terminal of memristor connecting achieves OR and XOR logic simultaneously. Furthermore, these two kinds of hybrid memristor-CMOS XOR logics are further used to build two kinds of single-bit full adders, and the adder circuits are verified by SPICE simulation. Our proposed full adder circuits have a smaller area and lower energy consumption compared to the CMOS technology.
