    Abstract: A semiconductor memory device comprises a cell structure and a peripheral circuit structure electrically connected to the cell structure. The peripheral circuit structure comprises an active region, a first gate structure comprising a first gate insulating layer intersecting the active region and in contact with the active region, a second gate structure comprising a second gate insulating layer spaced apart from the first gate structure, and in contact with the active region, and a source/drain region between the first gate structure and the second gate structure. A thickness of the first gate insulating layer is less than a thickness of the second gate insulating layer. The source/drain region comprises a first region adjacent to the first gate structure and a second region adjacent to the second gate structure. A depth of the first region is equal to a depth of the second region.
