Assessment of a universal logic gate and a full adder circuit based on CMOS-memristor technology

Abstract:

The study of memristor-based digital logic circuits is a new approach in non-conventional computation frameworks because of the memristor's properties, especially the ability to store data and perform logic operations. Using memristors, in this work, we have analyzed in terms of variability basic AND/OR Universal Logic Gates (ULG) and a Full adder implementation at the circuit-level in LT-spice. We first implement and calibrate a memristor's model with data obtained from IV curves of HfO2-based ReRAM to do it. The data demonstrate that although buffers are used to restore the signal, memristors variability affects the output voltage and the circuit's performance.
