The advancement of memristor technologies has recently attracted huge interest in exploiting their superior potential properties for enabling hybrid memristor-CMOS systems. This work presents a memristor-based Pass Gate - mPG, as a primitive cell as well as its deployment for implementing programmable routing switches targeting FPGAs. The mPG, consists of a transistor and output buffer(s) and can be used to discriminate resistance states for both binary and multi-state memristor technologies without additional circuitry. The proposed routing structure eliminates leakage current and avoids degrading memristor's characteristics due to voltage drops, which are essential factors for building reliable large-scale digital systems like FPGAs. Simulation results of mPG-based switches show that the gate can be deployed for a wide range of memristor resistance with a switching delay in the subnanosecond range. Physical implementations of the proposed primitive demonstrate savings of about 50% of the design in comparison to standard CMOS designs.
