The DS combination can be done 3 ways. First the word line can be extended below the D and then the "S curve" added. Secondly the "S curve" can be draw on the right send of the D's horizontal bar. Finally the Second form of the "S curve" can be drawn out of the right side of the D's horizontal bar and then continued into the word line.
