Design of digital functional blocks using hybrid memristor structures

The memristor device has emerged as the missing fourth fundamental circuit element after resistor, inductor and capacitor. Various implementations of memristors have been reported, with the one using a TiO2 layer sandwiched between two platinum electrodes considered to be most promising. Because of its very small feature sizes and low power consumption, it is projected to replace CMOS technology in several application areas. Various memory and logic design styles using memristors have been reported. A hybrid technology that combines memristors with CMOS gates is promising, and can be fabricated on the same silicon wafer. The present paper proposes the designs of various functional blocks like multiplexers, encoders and decoders using the hybrid memristor structure, with analyses regarding their design complexities. The design methodology is general, and can be used to synthesize arbitrary functional blocks as well.
