SPICE model for complementary resistive switching devices based on anti-serially connected quasi-static memdiodes

•Complementary Resistive Switching (CRS) takes place when two memristive devices are anti-serially connected forming a single functional structure.•The CRS structure is proposed as a way of reducing the sneak-path conduction problems in crossbar arrays.•The Quasi-Static Memdiode Model (QMM) is considered for simulating CRS structures in the form of a six terminal subcircuit: three pins for I-V characteristics and the rest for the low-voltage conductance.•Special attention is paid to the simulation of the so-called table with legs hysteresis loop (resistance at fixed bias vs. write voltage).•The model is compact, simple, robust, and accurate.•The model for each single structure consists in two equations, one for the electron transport and a second equation for the memory state of the device.•The model script for the SPICE simulator is also provided.
