Resistive Switching Assisted by Noise

Abstract We extend results by Stotland and Di Ventra [1] on the phenomenon of resistive switching aided by noise. We further the analysis of the mechanism un-derlying the beneficial role of noise and study the EPIR (Electrical Pulse Induced Resistance) ratio dependence with noise power. In the case of internal noise we find an optimal range where the EPIR ratio is both maximized and independent of the preceding resistive state. However, when external noise is considered no beneficial effect is observed.
