Abstract:
A three-dimensional memory device includes an alternating stack of insulating layers and electrically conductive layers, memory opening fill structures vertically extending through the alternating stack in a memory array region, and an electrically conductive spacer extending vertically and electrically connecting a first drain-select-level electrically conductive layer to a second drain-select-level electrically conductive layer.
