In an embodiment, some of the plurality of first contact plugs CP1 may be connected to the same first vertical line VL1v among the plurality of first vertical lines VL1v. In an embodiment, as shown in
The second voltage line VL2 may include a plurality of second vertical lines (also referred to as second perpendicular lines) VL2v each extending in the first direction DR1. Because the second contact plug CP2 is connected to the second voltage line VL2 to which a second initialization voltage is applied, the second contact plug CP2 may be connected to the second vertical line VL2v.
In an embodiment, some of the plurality of second contact plugs CP2 may be connected to the same second vertical line VL2v among the plurality of second vertical lines VL2v. In an embodiment, as shown in
