Hi everyone,
i worked in DDR2 and DDR3 Routing but. i studied some document related to DDR. For DDR3 Fly by (Daise chain) Topology is the best.but in DDR2 Address groups are routed in T-topology.
Here i attached DDR2 image. T-topolgy used.why we should not route the address signal group in Daisy chain topology ?? for DDR2. what is the different.
