Abstract
Methods of fabricating integrated circuit memory cells and integrated circuit memory cells are disclosed. An integrated circuit memory cell can be fabricated by forming a cup-shaped electrode on sidewalls of an opening in an insulation layer and through the opening on an ohmic layer that is stacked on a conductive structure. An insulation filling member is formed that at least partially fills an interior of the electrode. The insulation filling member is formed within a range of temperatures that is sufficiently low to not substantially change resistance of the ohmic layer. A variable resistivity material is formed on the insulation filling member and is electrically connected to the electrode.
