Analysis of the effect of boron doping on GeTe Phase Change Memories

Abstract

For the first time, we evaluate the electrical behavior of boron doped GeTe Phase-Change Memories (PCM). Our results demonstrate 25% RESET current reduction and excellent resistance contrast between SET and RESET states with B doping. A further benefit of controlled SET dynamics makes it favorable for MLC applications. Finally, we demonstrate that boron doped GeTe phase change materials maintain good device endurance reliability.
