Abstract:
1. A method for producing a nonvolatile memory element having the following steps: preparation of a carrier material; formation of an auxiliary layer having a top; formation of a depression in the auxiliary layer; filling of the depression substantially completely with a first electrically conductive material for forming a first electrode; formation of at least one field amplification structure at the first electrode, wherein in the step of formation of the at least one field amplification structure comprises: formation of a conductivity state changeover material on the first electrode with the at least one field amplifier structure, after which at least two different conductivity states prevailing in the conductivity state changeover material, between which changeover can be repeatedly effected by the application of predetermined programming voltages; and formation of a second electrically conductive electrode on the conductivity state changeover material.
