Abstract

A nonvolatile resistive memory element includes an oxygen-gettering layer. The oxygen-gettering layer is formed as part of an electrode stack, and is more thermodynamically favorable in gettering oxygen than other layers of the electrode stack. The Gibbs free energy of formation (ΔfG°) of an oxide of the oxygen-gettering layer is less (i.e., more negative) than the Gibbs free energy of formation of an oxide of the adjacent layers of the electrode stack. The oxygen-gettering layer reacts with oxygen present in the adjacent layers of the electrode stack, thereby preventing this oxygen from diffusing into nearby silicon layers to undesirably increase an SiOinterfacial layer thickness in the memory element and may alternately be selected to decrease such thickness during subsequent processing.
