Milo, well, IBM will have good stuff to licence to others as well as for their own use. 100 Ghz, I wonder if it will work with memory as well? I somehow doubt it since memory is not bipolar. Looks like a whole new design arena with all kinds ofseparated timing loops etc as at 100 ghz a wavelength is .003 meters or 3 MM(300,000,000 chopped into 100 billion bits makes each one that long) and that means all the traces are strongly suject to stripline microwave design rules in terms of matching Z and termination etc. At 2 ghz the wavelength is 150 MM, a whole lot longer and far less susceptable to microwave design rules. One hopes they will find a memory that can keep up with it, and not just small cache sectors, main memory. Lots of work to do, not as easy as just a simple material change and it now runs at 100 Ghz.
