Abstract

The embodiments herein describe technologies of initializing resistive memory devices (e.g., non-volatile and volatile memory devices). In one method, a first voltage is applied across a resistance change material of a memory cell to form an initial filament and multiple cycles are performed to condition the initial filament. Each of the multiple cycles includes: applying a second voltage with a first polarity across the resistance change material; and applying a third voltage with a second polarity across the resistance change material.
