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

In the issue of Advanced Intelligent Systems n/a (2025), e202501018 (early access), a research team by Rana Walied Ahmad, Solomon Amsalu Chekol, Julius Rasbach, Susanne Hoffmann-Eifert, Stephan Menzel published the article "Compact Modeling of Volatile-Switching Electrochemical Metallization Memory Cells by Means of the Electromotive Force".

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.
