a new approach - and a novel solution - to many of these issues.
The ITRS provides an excellent set of benchmarks that allow us to look ahead to examine the longevity of technology solutions over the next 14 years. They provide a robust quantitative framework to link the major technology and applications goals. Some current structures steadily decrease in viability and newcomers such as the PMCm already have many of the attributes that will be needed for the more distant roadmap targets.
