Methods and systems for fast, low power PCM memory using a bitline precharge scheme in which unselected bitlines are driven to predetermined voltages and a selected bitline is set to ground, such that when selected and unselected bitlines are shorted together, the selected bitline is charged to a PCM sense voltage. Inventive methods and systems do not require a precharge voltage regulator to drive selected bitlines to a sense voltage. |
