A memory element can include a first electrode; at least one switching layer formed over the first electrode; a second electrode layer; and at least one conductive cap layer formed over the second electrode layer having substantially no grain boundaries extending through to the second electrode layer; wherein the at least one switching layer is programmable between different impedance states by application of electric fields via that first and second electrode. Methods of forming such memory elements are also disclosed.

Memory elements having conductive cap layers and methods therefor

In one embodiment of the present invention, a resistive switching device includes a first electrode disposed over a substrate and coupled to a first potential node, a switching layer disposed over the first electrode, a conductive amorphous layer disposed over the switching layer, and a second electrode disposed on the conductive amorphous layer and coupled to a second potential node.

Resistive switching devices having a switching layer and an intermediate electrode layer and methods of formation thereof

A memory element programmable between different impedance states can include a first electrode layer comprising a semimetal or semiconductor (semimetal/semiconductor); a second electrode; and a switch layer formed between the first and second electrodes and comprising an insulating material; wherein atoms of the semimetal/semiconductor provide a reversible change in conductivity of the insulating material by application of electric fields.

Nonvolatile memory elements having conductive structures with semimetals and/or semiconductors

Structures and methods of operating a resistive switching memory device are disclosed herein. In one embodiment, a resistive switching memory device can include: (i) a plurality of resistive memory cells, where each of the resistive switching memory cells is configured to be programmed to a low resistance state by application of a first voltage in a forward bias direction, and to be erased to a high resistance state by application of a second voltage in a reverse bias direction; and (ii) a sensing circuit coupled to at least one of the plurality of resistive memory cells, where the sensing circuit is configured to read a data state of the at least one resistive memory cell by application of a third voltage in the forward bias direction or the bias reverse direction.
