Abstract :
A 0.8- mu m CMOS sea-of-gates (SOG) array with first-level wiring channels perpendicular to transistor rows and 40 0K transistors is integrated on a 6*7-mm2 chip. Implementation of a 64-bit multiplier shows 60-percent gate utilization and density of 1410 G/mm2. The wiring length of the multiplier is 70 percent of that in a conventional SOG.
