Claim 19:
20. A vertical memory device, comprising:
a substrate;
a plurality of channels extending lengthwise in a first direction substantially vertical to a top surface of the substrate;
a plurality of gate lines arranged and spaced apart from one another along the first direction, each of the plurality of gate lines extending lengthwise in a second direction, and the plurality of gate lines surrounding the channels;
a plurality of common wirings electrically connected to the gate lines, each of the plurality of common wirings extending lengthwise in a third direction crossing the second direction;
a plurality of first contacts extending lengthwise in the first direction, wherein a first end of each first contact is connected to a corresponding common wiring from among the common wirings, and a second end of each first contact is connected to a corresponding gate line from among the gate lines,
wherein the second ends of the first contacts disposed at different levels from one another,
wherein an uppermost gate line from among the gate lines is connected to a corresponding common wiring from among the common wirings via a corresponding first contact from among the first contacts;
a plurality of first signal wirings electrically connected to lower gate lines from among the gate lines via the common wirings; and
a plurality of second signal wirings electrically connected to upper gate lines from among the gate lines via the common wirings,
wherein the second signal wirings are disposed higher than the first signal wirings in the first direction,
wherein the first signal wirings are electrically connected to adjacent first common wirings from among the common wirings, the adjacent first common wirings being disposed in the second direction, and
wherein the second signal wirings are electrically connected to adjacent second common wirings from among the common wirings, the adjacent second common wirings being disposed in the second direction.
