"Designed to keep Moore's Law alive...."
Moore's Law can't be kept alive, as it never really existed. Moore made a passing comment about the rate at which fabrication was advancing, quite secondarily to another topic that was (to him) more interesting. Typically, the minor comment was latched onto and the major point has been entirely forgotten.
There's absolutely no scientific, engineering or logical basis for there to be a constant rate of chip density increase, so "Moore's Law" is really nothing other than fabricators' PR hype.
