Abstract
In some embodiments, the present disclosure relates to an integrated chip. The integrated chip includes a bottom electrode disposed over one or more interconnects and a diffusion barrier layer on the bottom electrode. The diffusion barrier layer has an inner upper surface that is arranged laterally between and vertically below an outer upper surface of the diffusion barrier film. The outer upper surface wraps around the inner upper surface in a top-view of the diffusion barrier layer. A data storage structure is separated from the bottom electrode by the diffusion barrier layer. A top electrode is arranged over the data storage structure.
