JART VCM Rth

This model is an extension of the existing JART (Jülich Aachen Resistive Switching Tools) VCM v1b model, by incorporating state-dependent effective thermal resistance (Rth,eff) based on an electro-thermal continuum model. This enables precise modeling of multilevel behavior and includes the variability in switching cycles to reflect experimental conditions. Figure 1(JART_VCM_Rth_Fig1.jpg) shows that the validation with TaOx-based VCM devices co-integrated with 180 nm n-MOS transistors demonstrates the model’s accuracy, achieving consistent multilevel programming across 7-states and capturing cycle-to-cycle variability effectively.
