Abstract
Memory devices incorporating bridged word lines are described. The memory devices include a plurality of active regions spaced along a first direction, a second direction and a third direction. A plurality of conductive layers is arranged so that at least one conductive layer is adjacent to at least one side of each of the active regions along the third direction. A conductive bridge extends along the second direction to connect each of the conductive layers to one or more adjacent conductive layer. Some embodiments include an integrated etch stop layer. Methods of forming stacked memory devices are also described.
