A design structure tangibly embodied in a machine readable medium for designing, manufacturing, or testing an integrated circuit includes a plurality of bit line structures, a plurality of word line structures intersecting said plurality of bit line structures to form a plurality of cell locations, and a plurality of cells located at said plurality of cell locations, each of said cells being selectively coupled to a corresponding bit line structure under control of a corresponding word line structure, each of said cells comprising a logical storage element having at least a first n-type field effect transistor and at least a first p-type field effect transistor, wherein said at least first n-type field effect transistor is formed with a relatively thick buried oxide layer sized to reduce capacitance of said bit line structures, and said at least first p-type field effect transistor is formed with a relatively thin buried oxide layer.
