Implementation of combinational circuits via material implication using memristors

Abstract

Memristor is a new nanoelectronic device that has become very popular at recent times for its non-volatility, better alignment and excellent scalability properties. Various research works are going on designing of logic circuits, digital memory and neuromorphic systems using this nano device. Both pure and hybrid approaches are followed for the design purpose. Material implication logic brings in the motivation for exploring memristors in the area of logic design. In this work material implication logic has been applied to design complex combinational circuits like demultiplexer, encoder, priority encoder, decoder and magnitude comparator using memristors. Both serial and parallel approaches have been used for the design purpose and the parallel implementations require lesser step counts than their serial counterparts. Also the designs presented occupy lesser area than their conventional CMOS-peers.
