sentences:  Other papers followed shortly.Boysel recalls that four-phase dynamic logic allowed him to achieve 10X the packing density, 10X the speed, and 1/10 the power, compared to other MOS techniques being used at the time (metal-gate saturated-load PMOS logic), using the first-generation MOS process at Fairchild.There are basically two types of logic gate – a '1' gate and a '3' gate.
