a. Stated timing for worst case Propagation Delay over process variation at V
a. The loads presented in
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 8 loads per
half column. The global clock has up to 11 loads per half column.
Delay Factor, K, for speed grade, voltage and temperature settings as specified in the Operating Range.
