In this paper, we propose a CMOS-memristor hybrid circuit that can perform 4-bit multiplication for future energy-efficient computing in nano-scale digital systems. The proposed CMOS-memristor hybrid circuit is based on the parallel architecture with AND and OR planes. This parallel architecture can be very useful in improving the power-delay product of the proposed circuit compared to the conventional CMOS array multiplier. Particularly, from the SPECTRE simulation of the proposed hybrid circuit with 0.13-mm CMOS devices and memristors, this proposed multiplier is estimated to have better power-delay product by 48% compared to the conventional CMOS array multiplier. In addition to this improvement in energy efficiency, this 4-bit multiplier circuit can occupy smaller area than the conventional array multiplier, because each cross-point memristor can be made only as small as $4F^2$.

This paper presents design methodology for Memristor-CMOS circuits and its application to primitive IPs design. We proposed a Memristor model and designed basic elements, Memristor AND/OR gates. The primitive IPs based on a Memristor-CMOS technology is proposed for a Memristive system design. The netlists of IPs are extracted from the layouts of Memristor-CMOS and is verified with SPICE-like Memristor model under $0.18{\mu}m$ CMOS technology. As a result, an example design Memristor-CMOS full adder has only 47.6 % of silicon area compare to the CMOS full-adder.
