  • Abstract
    In this work we apply a physical model based on charge transport and molecular mechanics/dynamics simulations to investigate the physical mechanisms governing the RRAM forming and switching operations. The proposed model identifies the major driving forces controlling conductive filament (CF) formation and changes during RRAM switching, thus providing a tool for investigation and optimization of RRAM devices.
