Abstract
A semiconductor device structure includes a metallization stack that has one or more patterned metal layers in a logic area and a memory area. At least one memory device is disposed above the metallization stack. A first level logic metal layer is coupled to a patterned metal layer of the one or more patterned metal layers in the logic area. A first level memory metal layer is formed above the first level logic metal layer and is coupled to a top electrode of the memory device stack. A distance between the one or more patterned metal layers in the logic area and the first level logic metal layer is smaller than the distance between the one or more patterned metal layers in the memory area and the first level memory metal layer.
