A transient circuit model for a phase change memory element

, , ,


A transient lumped element model for a phase change memory (PCM) cell is developed for use in a circuit simulator. Unlike existing models, this model calculates threshold voltage and off-state resistance drift as found in PCM-cells. After an explanation of the model, simulations results are shown and compared with measurements.
