    摘要: Multiple modes of operation in a cross point array. The invention is a cross point array that uses a read voltage across a conductive array line pair during a read mode. The read voltage produces a read current that is indicative of a first program state when the read current is at a first level and indicative of a second program state when the read current is at a second level. The read current is ineffective to produce a change in program state. A first voltage pulse is used during a first write mode if a change from a second program state to a first program state is desired. A second voltage pulse is used during a second write mode if a change from the first program state to the second program state is desired.

    摘要: Providing a cross point, memory array with memory plugs exhibiting a characteristic hysteresis. The memory plugs exhibit a hysteresis that, in the low resistive state, the first write threshold voltage is the point above which any voltages applied across the memory plug have substantially no effect on the resistive state and below which a voltage pulse will alter the resistance of the memory plug. Similarly, in the high resistive state, the second write threshold voltage is the point below which any voltages applied across the memory plug have substantially no effect on the resistive state and above which a voltage pulse will alter the resistance of the memory plug. The read voltages applied to the memory plug are typically above the first write threshold voltage and lower than the second write threshold voltage.
