Comparison of PN Diodes and FETs as Phase Change Memory (PCM) Driving Devices
In this study,the current driving capability of PN diodes and Field Effect Transistors (FETs) for Phase Change Memory (PCM) applications is investigated. To have a fair comparison,vertical gate-all-around (GAA) MOSFETs with similar cross-section as the PN diodes are selected for comparison. Through extensive 3-D device simulations have been performed based on existing experimental data from the 90nm to 22nm technology node,PN diodes are found to be a better choice for delivering higher programming currents down to 22nm technology node due to the higher effective cross-sectional area of current flow. In addition,the GAA MOSFETs are subject to serious cross-talk issues that may limit their performance in PCM applications.
