Abstract
An integrated circuit including a substrate having a memory area and a non-memory area. An embedded memory is fabricated on the substrate within the memory area. First and second semiconductor cells are fabricated on the substrate within the non-memory area. An electromagnetic shield covers substantially memory area. A routing layer is fabricated over the memory and non-memory areas and over the electromagnetic shield. A signal wire is electrically coupled between the first and second semiconductor cells and has a conductive segment which is routed within the routing layer and extends over the memory area.
