Abstract
Methods and structures of a three-dimensional memory device are disclosed. In an example, the memory device includes a substrate, a first tier of conductor layers of a first length comprising a first plurality of conductor layers extending along a first direction over the substrate. The first direction is substantially parallel to a top surface of the substrate. In some embodiments, the memory device also includes at least one connection portion conductively connecting two or more conductor layers of the first tier, and a first metal contact via conductively shared by connected conductor layers of the first tier and connected to a first metal interconnect.
