Patent ID: 8314003

Claim:
A method of fabricating a nonvolatile memory device, the method comprising: forming a plurality of first external electrodes and a plurality of second external electrodes on a substrate, the first external electrodes and the second external electrodes extending substantially in parallel with a face of the substrate and being isolated from each other; forming an insulating layer that covers the first external electrodes and the second external electrodes; forming a plurality of contact holes through the insulating layer between the first external electrodes and the second external electrodes, the contact holes being substantially perpendicular to the face of the substrate; forming a plurality of variable resistors that directly contact the first external electrodes and the second external electrodes; and forming a plurality of internal electrodes by depositing a conductive material in the contact holes, the internal electrodes contacting the variable resistors and extending in a direction substantially perpendicular to the face of the substrate.
