Abstract
A three-dimensional memory device includes a substrate, conductive layers and insulating layers, a storage layer, a first channel, a second channel and a first conductive plug. The conductive layers and insulating layers are alternately stacked over the substrate to form a multi-layer stacked structure. The storage layer penetrates through the multi-layer stacked structure, and has a first string portion and a second string portion that are spaced from each other. The first channel is located on a lateral side of the first string portion. The second channel is located on a lateral side of the second string portion. The first channel and the second channel have an upper channel portion and a lower channel portion. The first conductive plug is interconnected between the upper channel portion and the lower channel portion.
