    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.
