Nanometer-scale system design challenges: Bridging the gap from devices to architectures

Next generation logic switching devices are expected to rely on radically new technologies mainly due to the increasing difficulties and limitations of state-of-the-art CMOS switches, which, in turn, will also require innovative circuit and system architectures, and design methodologies that are distinctly different from those used for CMOS technologies. In this paper, we discuss a few specific examples of logic design platforms that exploit the structural regularity that is predicted to dominate SiNW based systems, as well as the ambipolarity of devices that can be utilized to achieve higher logic versatility for the same number of components.
