Abstract
A semiconductor device includes a substrate, plural active areas, plural bit lines and plural dummy bit lines. The substrate includes a cell region and a periphery region, and the active areas are defined on the substrate. The bit lines are disposed on the substrate, within the cell region and across the active areas. The dummy bit lines are disposed at a side of the bit lines, wherein the dummy bit lines are in contact with each other and have different pitches therebetween.
