Abstract :
In this letter, we present the characterization and modeling of the reset statistics of Pt/NiO/W resistive random access memories. The experimental observations show that the Weibull slopes of both Vreset and Ireset cumulative distributions increase linearly with 1/Ron. The value of Vreset63% is roughly independent of Ron while Ireset63% increases with 1/Ron. Fully analytical cell-based models based on the thermal dissolution of conductive filament are proposed for the reset switching statistical distributions, which can account for the experimental results with a remarkable agreement.
