a. The array distributed networks consist of 40 half columns and the global distributed networks consist of 44 half columns, each driven
by an independent buffer. The number of half columns used does not affect clock buffer delay. The array clock has up to eight loads
per half column. The global clock has up to 11 loads per half column.
