Abstract
A three-dimensional memory device includes an alternating stack of insulating layers and electrically conductive layers located over a substrate and memory stack structures extending through the alternating stack. Each memory stack structure includes a memory film and a vertical semiconductor channel. An isolation trench laterally extends along a horizontal direction and divides at least two topmost electrically conductive layers. Two conductive rail structures are located on lengthwise sidewalls of the isolation trench and are electrically shorted to respective segments of the at least two topmost electrically conductive layers.
