Abstract
Memory devices and methods for operating such devices are described herein. A method as described herein includes applying a bias arrangement to a memory cell to change the resistance state from a higher resistance state to a lower resistance state. The bias arrangement comprises a first voltage pulse and a second voltage pulse across the phase change memory element, the second voltage pulse having a voltage polarity different from that of the first voltage pulse.
