Abstract: Technology is disclosed for a memory system having a cross-point array with threshold switching selector memory cells. Each memory cell has a two-terminal threshold switching selector memory element that may be programmed to two different on-state conductances in order to store information. One bit value may be represented by a high-resistance state (HRS) when in the on-state and another bit value may be represented by a low-resistance state (LRS) when in the on-state. In one aspect, a conditioning signal is applied to the memory cell prior to programming. Applying a program signal with the opposite polarity as the conditioning signal may result in a higher conductance in the on-state than applying a program signal with the same polarity as the conditioning signal. The memory element may also serve as a selector for the memory cell. The memory element may include an Ovonic Threshold Switch (OTS).

Abstract: Technology is disclosed for improving read margin in a cross-point memory array. Drive transistors pass a read and write currents to the cross-point memory array. The read current charges a selected word line to turn on a threshold switching selector of a selected memory cell. While the threshold switching selector is on, the current (read or write) passes through the selected memory cell. The memory system applies a smaller overdrive voltage to the drive transistor when the drive transistor is passing the read current than when the drive transistor is passing the write current. A smaller overdrive voltage increases the resistance of the drive transistor which improves read margin. Increasing the resistance of the drive transistor increases the resistance seen by the threshold switching selector in the selected memory cell, which reduces the Ihold of the threshold switching selector. Reducing Ihold of the threshold switching selector improves read margin.
