Abstract:
1. A method of making a resistive switching memory device on a substrate, the method comprising: fabricating the resistive switching memory device in a single chamber, wherein the fabricating comprises: forming a first layer above the substrate, the first layer operable as a first electrode of the resistive switching memory device; forming a second layer above the first layer, the second layer operable as a resistive switching layer of the resistive switching memory device; forming a third layer above the second layer, the third layer operable as a current limiting layer of the resistive switching memory device; and forming a fourth layer above the third layer, the fourth layer operable as a second electrode of the resistive switching memory device, wherein the first layer and the fourth layer are formed from different materials; and wherein the second layer, the third layer, and the fourth layer are formed under a same range of substrate temperature range process conditions, chamber pressure range process conditions, and carrier gas purge range process conditions.
