> First, silicon-gate transistors were smaller, faster, and more reliable.
> Second, silicon-gate chips had a layer of polysilicon wiring in addition to the metal wiring; this made chip layouts about twice as dense.8
> Third, metal-gate circuitry required an additional +12 V power supply.
This implies silicon-gate chips DO NOT require the additional power supply.
