Design of a Simple Readout Circuit for Resistive Switching Memristors Based on CMOS Inverters

In this paper a CMOS reading circuit for memristor-based RRAM (Resistive Random Access Memory) cell is described. Simulations for one cell, 4 by 4 nMOS-accessed-array and extension to N by N nMOS-accessed-array are presented. The proposed circuit is based on CMOS inverters, which result in a simple low area architecture and in a non-destructive operation. Resistive switching memristor is used as reading reference. Simulations were performed in $0.5\ \mu \text{m}$ and 180 nm CMOS technology and using memristor model available in bibliography.
