Abstract: A three-dimensional array of memory elements that reversibly change a level of electrical conductance in response to a voltage difference being applied across them. The memory elements can be set to a low resistance state and reset to a high resistance state during standard operation by biasing appropriate voltages on the word lines and bit lines. Prior to standard operation, the memory elements undergo a forming operation, during which current through the bit lines is limited. A forming voltage is applied to the memory elements during forming with a polarity such that a higher voltage is applied to anodes and a lower voltage to cathodes.

Abstract: The manufacturing of the non-volatile storage system includes depositing one or more layers of reversible resistance-switching material for a non-volatile storage element. Prior to operation, either during manufacturing or afterwards, a forming operation is performed. In one embodiment, the forming operation includes applying a forming voltage to the one or more layers of reversible resistance-switching material to form a first region that includes a resistor and a second region that can reversibly change resistance at a low current, the resistor is formed in response to the forming condition and is not deposited on the device. In some embodiments, programming the non-volatile storage element includes applying a programming voltage that increases in voltage over time at low current but does not exceed the final forming voltage.

Abstract: A resistance-switching memory cell is programmed in a set or reset operation which tests the stability of the cell. A first programming phase using program voltages which increase in magnitude or duration until a program verify test is passed. A stability test phase is then performed to evaluate a stability of the memory cell. The stability test phase determines whether the memory cell is weak and likely to transition out of the set or reset state by applying one or more disturb pulses and performing one or more stability verify tests. The disturb pulses can have a reduced magnitude or duration compared to the program voltages. If the stability test phase indicates the memory cell is not stable, a second programming phase is performed. If the stability test phase indicates the memory cell is stable, the operation is concluded.

Abstract: A re-writable resistance-switching memory cell includes first and second capacitors in series. The first and second capacitors may have balanced electrical characteristics to allow nearly concurrent, same-direction switching. The first capacitor has a first bipolar resistance switching layer between first and second conductive layers, and the second capacitor has a second bipolar resistance switching layer between third and fourth conductive layers. The first and third conductive layers are made of a common material, and the second and fourth conductive layers are made of a common material. In one approach, the first and second bipolar resistance switching layers are made of a common material and have common thickness. In another approach, the first and second bipolar resistance switching layers are made of materials having different dielectric constants, but their thickness differs in proportion to the difference in the dielectric constants, to provide a common capacitance per unit area.
