Effect of Hf Metal Layer on the Switching Characteristic of HfOX-based Resistive Random Access Memory

Elmira Shahrabi, Yusuf Leblebici, Jury Sandrini, Behnoush Attarimashalkoubeh, Marios Barlas

In this study, we propose the insertion of an ultrathin Hf layer at the interface between TiN (top electrode) and HfOX (electrolyte), and then studied its effect on the device electrical properties. In order to obtain the desired switching characteristics, ...
