What are the Challenges in Developing PCM Devices?
Despite its potential, PCM technology faces several challenges. One of the primary issues is the high power consumption required for the phase transition process. Additionally, the material stability and resistance drift over time can affect the reliability of data storage. Scaling down the PCM cells to nanometer dimensions also introduces challenges related to heat management and cross-talk between adjacent cells. Researchers are actively working on addressing these challenges through advanced material engineering and novel device architectures.
