Abstract :
This paper proposes a new macromodel that takes into account the threshold switching and the resistance recovery processes in addition to the drift behavior of a Phase Change Memory (PCM). Simulation results are provided for both DC and drift behaviors; they show that the proposed macromodel is very accurate at a small error when compared with data from experimental devices. A sensitivity analysis of the macromodel is also performed to show its operation with respect to parameter variations. The model is suitable for circuit design based on PCM devices.
