Abstract A compact spice model of the phase change memory with the crystalline fraction as the switching by Verilog-A language is proposed and demonstrated. The model can simulate not only the resistance change by the different electrical pulse, but also the temperature profile and crystalline fraction during programming operation. The simulated resistance as a function of the amplitude of programming voltage pulses is in good agreement with the experimental data.
