A Programmable Circuit Based on the Combination of VTM Cellular Crossbars

Abstract

This paper proposes a design of a programmable circuit based on the combination of crossbar arrays using the VTM-NAND/AND logic gates. The novelty of this work is the utilization pipeline technique for the proposed arrangements. The important feature of this method is multiple instructions overlap during execution where designed cells will never be idle, that causes an increase in the number of instructions executed simultaneously and speed of calculations. All of the digital gates and proposed circuits are evaluated using an advanced memristor model with a modified Biolek window and a voltage-dependent variable exponent.
