    摘要: A method for programming a non-volatile memory device includes providing an as-fabricated state-change device having an aluminum doped zinc oxide material first electrode, a p++ polysilicon material second electrode, and a zinc oxide (ZnO) material state-change material there between. A first amplitude bias voltage is applied to the first electrode of the as-fabricated state-change device causing the ZnO material to change form an as-fabricated state to a first state. A second amplitude bias voltage having an opposite polarity having an amplitude similar to the first amplitude is applied to cause the ZnO to change from the first state to a second state substantially similar as the as-fabricated state. A third amplitude bias voltage having a same polarity to the first bias voltage and having an amplitude dissimilar to the first bias voltage is applied to cause the ZnO to change from the second state to a third state.

    摘要: A method of suppressing propagation of leakage current in an array of switching devices. The method includes providing a dielectric breakdown element integrally and serially connected to a switching element within each of the switching device. A read voltage (for example) is applied to a selected cell. The propagation of leakage current is suppressed by each of the dielectric breakdown element in unselected cells in the array. The read voltage is sufficient to cause breakdown in the selected cells but insufficient to cause breakdown in the serially connected, unselected cells in a specific embodiment. Methods to fabricate of such devices and to program, to erase and to read the device are provided.

    摘要: A non-volatile memory device structure. The non-volatile memory device structure comprises a first electrode formed from a first metal material, a resistive switching element overlying the first electrode. The resistive switching element comprises a metal oxide material characterized by one or more oxygen deficient sites. The device includes a second electrode overlying the resistive switching layer, the second electrode being formed from a second metal material. The second electrode is made from a noble metal. The one or more oxygen deficient sites are caused to migrate from one of the first electrode or the second electrode towards the other electrode upon a voltage applied to the first electrode or the second electrode. The device can have a continuous change in resistance upon applying a continuous voltage ramp, suitable for an analog device. Alternatively, the device can have a sharp change in resistance upon applying the continuous voltage ramp, suitable for a digital device.

    摘要: Non-crystalline silicon non-volatile resistive switching devices include a metal electrode, a non-crystalline silicon layer and a planar doped silicon electrode. An electrical signal applied to the metal electrode drives metal ions from the metal electrode into the non-crystalline silicon layer to form a conducting filament from the metal electrode to the planar doped silicon electrode to alter a resistance of the non-crystalline silicon layer. Another electrical signal applied to the metal electrode removes at least some of the metal ions forming the conducting filament from the non-crystalline silicon layer to further alter the resistance of the non-crystalline silicon layer.
