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 underlying the beneficial role of noise and study the Electrical Pulse Induced Resistance (EPIR) 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.
