A memory device having a reduced-thickness phase change film is described
along with methods for manufacture. The device includes an electrode
element, in electrical contact with a phase change layer. The latter
element is formed from a memory material having at least two solid
phases. A top electrode element makes electrical contact with the phase
change layer at a location remote from the contact location of the
electrode element. This construction produces a current flow through the
phase change element in which at least a portion thereof lies in a path
transverse to the current flow path within the electrode element.
