Abstract:
Reset refresh techniques are described, which can enable reducing or canceling the drift of threshold voltage distributions exhibited by memory cells. In one example a memory device includes an array of memory cells. The memory cells include a chalcogenide storage material. The memory device includes hardware logic to program the memory cells, including logic to detect whether a memory cell is selectable with a first voltage having a first polarity. In response to detection that a memory cell is not selectable with the first voltage, the memory cell is refreshed the memory cell with a second voltage that has a polarity opposite to the first voltage. After the refresh with the second voltage, the memory cell can be programmed with the first voltage having the first polarity.

Claim (Index 9):
A memory device comprising:\n an array of memory cells, the memory cells including a self-selecting chalcogenide material; and hardware logic to program one or more of the memory cells, including logic to:\n apply a first voltage pulse to program a memory cell to a first logic value, and \n in response to a determination that the memory cell was not programmed to the first logic value with the first voltage pulse:\n apply a second voltage pulse having a polarity opposite to the first voltage pulse, the second voltage pulse to program the memory cell to a second logic value, and \n after application of the second voltage pulse, apply a third voltage pulse having the same polarity as the first voltage pulse to program the memory cell to the first logic value.
