6.3.4 Address & Control Signals
This group encompasses the memory address
MA[10:0], bank address BA[0], RAS, CAS and
write enable WE signals. The load of the DIMM
module on these signals is the most important one
and depends upon the type of SDRAM compo-

nents used (x4, x8 or x16) and whether the DIMM
module is single or dual row. The capacitive load-
ing of the SDRAM inputs alone for an x8 single
row DIMM will be about 30-40pF. An equivalent
circuit for the timing simulation is shown inFigure
6-14 Most of the delays are due to the PCB traces
and loading rather than the pad itself.
