[SI-LIST] SDRAM timing

Hi, all:

I  oftem see designer reel the PCB trace for equivalent length in SDRAM data
bus. I am very puzzled about it all the time  I think, for SDRAM data bus,
there is on need for equivalent trace length in SDRAM data bus. The timing
is determined by the longest data bus. For other SDRAM data bus, the short,
the better, and no need for equivalent. Do you think so?

Also where can I find some detailed guide for SDRAM and DDR tracing?

Thanks in advanced

Peter
