A semiconductor device or a memory which includes the same have a line pattern, and a contact plug, the line pattern including a first linear feature to which the contact plug is connected by design, and a second linear feature having a connecting portion and a dummy portion adjacent the location at which the contact plug is electrically connected to the first linear feature. A second contact plug is electrically connected to the connecting portion of the second linear feature of the line pattern. In the case of a misalignment error or the like, the first contact plug may also be electrically connected to the second linear feature of the line pattern but at the dummy portion thereof so as to not create a short circuit in that case. The dummy portion thus allows a sufficiently large process margin to be secured for the contact plug.
