全体主题 > Modeling and Simulation Technology

An approach on the formulation of the temperature sub-circuit of phase change memory (PCM) is developed for fast circuit simulations in this work. The traditional method using a sub-circuit can lead to significant increase of simulation time with the addition of an internal node. In contrast, the internal node can be eliminated by solving sub-circuit equations directly. The accuracy and transient simulation time for PCM circuits using different methods are compared validating the developed method.
