A neotype implemention method for CRS-based logic gates in crossbar array

Abstract

Recently, researchers have demonstrated that memristors can be used to implement latches and memory as well as programmable interconnects, logic circuits are also important application using memristors. In this paper, we propose a novel design for complementary resistive switch based stateful logic architecture. In the proposed method, five basic logic operations can be applied to passive crossbar arrays, which offered huge benefits in terms of scalability and area consumption. In addition, multi-input logic operation can be implemented successfully. Moreover, the proposed design applying CRS may reduce sneak paths, which corresponds to parasitic current paths that bypass the target storage element and may cause the array to be nonfunctional.
