  • Abstract
    An atomistic Monte-Carlo simulator is developed for TaOx-based resistive switching random access memory (RRAM) including both the generation & recombination effect of oxygen vacancy defects with oxygen ions and the phase change effect between Ta2O5 and TaO2. Using the developed simulation tool, the resistive switching characteristics of the bi-layered Ta2O5/TaOx RRAM are investigated. The typical self-compliance behavior measured in the bi-layered Ta2O5/TaOx RRAM is reproduced by considering the interaction between Ta2O5 and TaOx, indicating that TaOx layer plays a critical role to the self-compliance behavior.
