should be more elegant than that
I don't think there would be an additional size needed here. The actuators would simply allow redesign of the circuit path. If transistor A has B & C as a path, and C breaks, instead of the being dead the actuator just makes it where A only can go to B, and no longer "knows" about C.
This wouldn't be spare transistors, just the ability to work around dead ones.
Let me just add what utter crap this goal is - THERE IS NO MOORE'S LAW !!!!!
It does not exist and it is not a problem to be solved. This theory really should be called "Moore's Observation", as it has not even held out to be predictive. If you plot the release of CPU's to market, they do not have any designed doubling of transistor count. Competing CPU companies constantly come out with new designs. Transistor count also does not solely define processor performance. Further Memory bottlenecks and Hard Disk speeds are more of a bottle neck currently than transistor count is. Shrinking the die size 120nm to 45nm and smaller, Double Date Rate (using the rising and falling trough of the wavelength) using multiple cores and other technological tricks have enable the forward progress of processing power NOT Moore's Theory/Observation. I could just as easily plot the number of diseases cured by science, find a nice window of time they fit in, and Declare "McCoy's Law" - that the number of diseases will be cured by science will double every X years. or "Loki's Law" that system memory will double every two years. They do not have any predictive capability at all, and are not even sound theories. The idea that the US, humankind or even computing would be harmed by us not making Moore's Law self fulfilling is pure and utter garbage.
REG, please help, can we please stop using this uber-retarded term, or at least have a constant * added to the phrase?
* Not really a Law, or even a proven theory, more like a goal for forward progress.
