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.
