Abstract
The present disclosure relates to an integrated chip in some embodiments. The integrated chip includes a memory device disposed over a lower interconnect within one or more lower inter-level dielectric (ILD) layers over a substrate. An upper ILD layer laterally surrounds the memory device. An etch stop layer is disposed along a sidewall of the memory device and over an upper surface of the one or more lower ILD layers. An upper interconnect is arranged along opposing sides of the memory device. The upper interconnect rests of an upper surface of the etch stop layer. The upper surface of the etch stop layer is vertically below a top of the memory device.
