Abstract

Some embodiments relate to an integrated chip. The integrated chip includes a memory cell over a substrate, where the memory cell comprises a data storage structure. A conductive interconnect is over the data storage structure and comprises a first protrusion adjacent to a first side of the data storage structure, where the first protrusion comprises a flat bottom surface. A spacer structure is disposed on the first side of the data storage structure. The spacer structure directly contacts the flat bottom surface of the first protrusion.
