Abstract
A method is disclosed for driving a phase change memory device including a phase change resistor. The method includes applying a trigger voltage to the phase change resistor for a first write time to preheat the phase change resistor, applying a first write voltage to the phase change resistor for a second write time to control a first state of the phase change resistor, and applying a second voltage to the phase change resistor for a third write time to control a second state of the phase change resistor.
