Abstract :
In this work, a model is proposed to explain the variability of OxRAM devices, both in their high and low resistive states. This model is based on the calculation of a 3D resistance network, using trap assisted tunneling current. The stochastic nature of the resistance is captured by random placement of traps within a specific spatial distribution.
