Behavioral SPICE model for memristive crosspoint arrays operating in the nonlinear transport regime

Year: 2025

Type: article

Abstract: In this letter, a fully behavioral SPICE model for M × N memristive crosspoint arrays (CPAs) is presented. The proposed approach incorporates the current–voltage characteristics of the memdiode model for resistive switching devices, which can account for both the linear (low-voltage) and nonlinear (high-voltage) transport regimes of memristors. At low voltages, the model coincides with the conventional linear formulation based on matrix–vector multiplication (MVM) method. At high voltages, however, this algebraic operation is no longer valid. The model supports two operation modes depending on the requirements of the surrounding circuitry: voltage-controlled current source (VCCS) and voltage-controlled voltage source (VCVS). Current-controlled modes are also feasible for specific applications. Basic guidelines for applying these different modes are provided.
