Simulation study of dimensional effect on bipolar resistive random access memory

0
The dependency of the RRAM device electrical parameters such as set voltage, reset current and resistance on the RRAM cell dimensional scalability is investigated with Monte Carlo simulation to optimise the power consumption of bipolar RRAM. It is found in the simulation that the switching process in bipolar RRAM is related to the cell dimension in the region of 10 nm to 100 nm in terms of its horizontal length. The suppressing effect of existing conducting filament is also discussed. With optimal cell size sufficient initial resistance and a low forming voltage will be achieved, accelerating the feasibility of the high–density low–power RRAM.
