Abstract :
In this work key aspects of the electroforming in RRAM cells with HfO2 oxide and Pt electrodes are addressed. Specifically, transient measurements were performed on extremely short timescales to characterize systematically the forming time and the resistance after forming as a function of the voltage pulse geometry and the device area.
