Abstract :
A numerical model based on the finite element method for phase change memory including ovonic threshold switch and memory threshold switch is developed. The temperature distribution, phase fraction profiles in set operation and the programming resistance variation with currents are simulated respectively. By analyzing the programming properties of cells at different reset state, the impacts of the reset current to the programming characteristics are evaluated.
