Emerging devices for post-classical CMOS - from memory, logic to architectures

The pace of MOSFET scaling has been obviously accelerated recently, and the simple scaling of MOSFET will not work for higher integration and higher performance in future. The introduction of nonclassical CMOS design using new transistor structures and new materials is urgent. Moreover, new research work has started on the invention of fundamentally new information processing and storage for future integrated systems. In this paper, the present status of the research on emerging nonclassical CMOS, emerging memories, and emerging new architecture devices is reviewed. Special emphasis is placed on the nano-scale devices that positively utilize new physical phenomena in nanostructures.
