ABSTRACT:
The present invention relates to the use of a shaped bottom electrode in a resistance variable memory device. The shaped bottom electrode ensures that the thickness of the insulating material at the tip of the bottom electrode is thinnest, creating the largest electric field at the tip of the bottom electrode. The arrangement of electrodes and the structure of the memory element makes it possible to create conduction paths with stable, consistent and reproducible switching and memory properties in the memory device.
