Abstract
A method of forming a filament in a resistive random-access memory (RRAM) device includes applying a cell voltage across a resistive layer of the RRAM device, detecting an increase in a current through the resistive layer generated in response to the applied cell voltage, and in response to detecting the increase in the current, using a first switching device to reduce the current through the resistive layer.
