A discussion on the extension of Moore's Law

Both theory and ITRS predict that the scaling of conventional silicon CMOS is going to approach its ultimate. Several emerging devices based on different new mechanism are proposed as possible successors. But still, as classical 2-level switches, they have common limits of quantum uncertainty and thermodynamic fluctuation. In order to further enhance and improve the ability and performance of ULSI systems, either more efficient devices or processing systems with new model and architecture are required. In this article, these topics are briefly discussed in unified view of the product of device delay time and its power dissipation.
