چکیده
Memristors can be used as logic gates. No design methodology exists, however, for memristor-based combinatorial logic. In this paper, the design and behavior of a memristivebased logic gate – an IMPLY gate are presented and design issues such as the tradeoff between speed (fast write times) and correct logic behavior are described, as part of an overall design methodology. A memristor model is described for determining the write time and state drift. It is shown that the widely used memristor model a linear ion drift memristor is impractical for characterizing an IMPLY logic gate, and a different memristor model is necessary such as a memristor with a current threshold.

Memristors are novel electrical devices used for a variety of applications including memory, logic circuits, and neuromorphic systems. Memristive technologies are attractive due to the nonvolatility, scalability, and compatibility with CMOS. Numerous physical experiments have shown the existence of a threshold voltage in some physical memristors. Additionally, as shown in this paper, some appli...
