Abstract
Various embodiments of the present disclosure are directed towards an integrated chip including a memory cell overlying a substrate and comprising a top electrode. A sidewall spacer structure is disposed along sidewalls of the memory cell. The sidewall spacer structure comprises a first spacer layer on the memory cell, a second spacer layer around the first spacer layer, and a third spacer layer around the second spacer layer. The second spacer layer comprises a lateral segment adjacent to a vertical segment. The lateral segment abuts the top electrode and has a top surface aligned with or disposed below a top surface of the top electrode. A first conductive structure overlies the memory cell and contacts the lateral segment and the top electrode.
