Compact Modeling of Volatile-Switching Electrochemical Metallization Memory Cells by Means of the Electromotive Force

26 October 2025

A volatile-switching compact model of electrochemical metallization memory cells for neuromorphic architecture is developed and validated by reliable reproduction of device characterization measurements: I-V sweeps, SET kinetics, relaxation dynamics. The volatile-switching and relaxation features occur through a shifted ionic dynamic equilibrium induced by the electromotive force. It leads to a spontaneous filament dissolution for positive sub-equlibrium voltages.
