description Memory devices comprise a lower layer that extends across a cell array region and across a peripheral region and that includes a flat outer surface from the cell array region to the peripheral region. A signal transfer conductor layer extends in the cell array region beneath the flat outer surface of the lower layer and extends in the peripheral region above the flat outer surface of the lower layer. An insulating layer is provided on the lower layer, including a flat outer surface from the cell array region to the peripheral region. A flat stopper layer is provided on the flat outer surface of the insulating layer and extending across the cell array region and the peripheral region. Related methods are also provided.
