Abstract:
1. A method for producing a nonvolatile memory element, comprising: providing a carrier material; forming an auxiliary layer; forming a depression in the auxiliary layer; filling the depression with a first electrically conductive material to form a first electrode; forming at least one field amplification structure at the first electrode, wherein the formation of the at least one field amplification structure comprises: forming a conductivity state changeover material layer on the first electrode with the at least one field amplifier structure in such a way that a further adapted depression remains in the region of the depression, after which at least two different conductivity states prevailing in the conductivity state changeover material, between which changeover can be repeatedly effected by an application of predetermined programming voltages; and forming a second electrically conductive electrode on the changeover material layer.
