Claim Text:
1. A resistive switching device comprising: a first electrode coupled to a first potential node, the first electrode disposed over a substrate; a second electrode coupled to a second potential node; a switching layer disposed between the first electrode and the second electrode and contacting the first electrode, wherein the switching layer comprises a first impedance in a first state of the resistive switching device and a second impedance in a second state of the resistive switching device, the second state being different from the first state; and a conductive amorphous layer disposed between the switching layer and the second electrode and contacting the switching layer, wherein the conductive amorphous layer comprises a substantially same impedance in the first state and the second state, wherein the second electrode is disposed over and contacts the conductive amorphous layer, and wherein the conductive amorphous layer comprises tellurium or selenium.
