In this letter, we show a compact model that describes the main electrical features of phase change memory (PCM) devices. The model coherently reproduces the behavior of both SET and RESET states with the description of the physics of involved phenomena for different bias and temperature conditions. For arbitrary programming pulses, the model is able to generate intermediate states with mixed phase distributions and, thus, with resistance values between the SET and RESET ones. The proposed… CONTINUE READING
