A method comprising forming a first dielectric layer over an electrode
formed to a first contact point on a substrate, the electrode having a
contact area; patterning the first dielectric layer into a body, a
thickness of the first dielectric layer defining a side wall; forming at
least one spacer along the side wall of the first dielectric body, the at
least one spacer overlying a portion of the contact area; forming a second
dielectric layer on the contact area; removing the at least one spacer;
and forming a material comprising a second contact point to the contact
area. An apparatus comprising a volume of programmable material; a
conductor; and an electrode disposed between the volume of programmable
material and the conductor, the electrode having a contact area coupled to
the volume of programmable material.
