I-V Simulation of Phase Change Memory

Rong Jin*, Houpeng Chen, Daolin Cai, Qian Wang, Xiaogang Chen, Zhitang Song


Abstract: This paper presents some simulation I-V curves for different electrode size. The curve is not a ohm characteristic curve, therefore the inner carrier distribution should be confirmed to get the accurate I-V curve, which can be solved by coupled Poisson’s equation, current continuous equation and the heat transfer equation. With the structure and size of phase change material, the I-V curve can be obtained through simulation. With the further simulation, a more suitable construction and size can be suggested.
