Abstract
The present disclosure, in some embodiments, relates to an integrated chip. The integrated chip includes a lower interconnect disposed within a dielectric structure over a substrate. A memory device includes a data storage structure disposed between a bottom electrode and a top electrode. The bottom electrode is electrically coupled to the lower interconnect. A sidewall spacer includes an interior sidewall that continuously extends from along an outermost sidewall of the top electrode to below an outermost sidewall of the bottom electrode. The sidewall spacer further includes an outermost sidewall that extends from a bottom surface of the sidewall spacer to above a top of the bottom electrode.
