Abstract
Various embodiments of the present disclosure are directed towards a method for forming an integrated chip, the method includes forming a memory cell stack over a substrate. The memory cell stack comprises a tunnel barrier layer, a free layer over the tunnel barrier layer, a capping dielectric layer over the free layer, and a conductive capping layer on the capping dielectric layer. A conductive shunting structure is formed along outer sidewalls of the free layer, outer sidewalls of the capping dielectric layer, and outer sidewalls of the conductive capping layer. A bottommost point of the conductive shunting structure in contact with the free layer is disposed above a bottom surface of the free layer.
