A compact model of diode array for Phase Change Memory

Abstract

In this paper, a compact diode array model for Phase Change Memory (PCM) application is presented. From the diode array structure and numerical simulation result, a quasi-physical compact model is proposed by combining the classical diode equation and simplified bipolar device formulation. This model results in accurate calculation of different leakage current components with parameter setting. Furthermore, the presented model is an open model structure, and can be applied in different fabrication process with the parameter extraction. All these characteristics make it useful in further study of physical mechanism of carrier transmissions in order to illustrate the device physics of such an array diode device.
