I'm not sure chip fabs are ever going to say Moore's law is dead -- I interned at Intel last summer, and Moore's law was pretty much all they could talk about. (In fact, they made very similar claims at the exact same conference [0]).
In fact, multiple gates can be created in the same transistor, in an effect SFN calls “multi-tunnel.” Multiple NOR and OR gates can thus be created from a single Bizen transistor, allowing creation of logic circuits with many fewer devices. This can result in a three-fold increase in gate density with a corresponding reduction in die size for integrated circuits based on the transistors. Summerland said that SFN is also creating a reduced device count processor architecture to enable analogue computing with Bizen transistors.
