Dynamic random access memory (DRAM) devices include first node pads and second node pads alternately arranged in a first direction on a substrate to form a first pad column. A width of the second node pads in a second direction, perpendicular to the first direction, is greater than a width of the first node pads in the second direction. Storage electrodes are electrically connected to the first node pads and the second node pads. Bit line pads may be arranged in the first direction on the substrate to form a second pad column. The second pad column is adjacent the first pad column and displaced therefrom in the second direction.
