7.7.2.3.5 Data Topologies and Routing Definition
No matter the number of DDR3 devices used, the data line topology is always point to point, so its
definition is simple.
7.7.2.3.5.1 DQS[x] and DQ[x] Topologies, Any Number of Allowed DDR3 Devices
DQS[x] lines are point-to-point differential, and DQ[x] lines are point-to-point singled ended. Figure 7-62
and Figure 7-63 show these topologies.
