Figure 8-8 shows the CK routing for four DDR3 devices placed on the same side of the PCB. Figure 8-9 shows the corresponding ADDR_CTRL routing.
To save PCB space, the four DDR3 memories may be mounted as two mirrored pairs at a cost of increased routing and assembly complexity. Figure 8-10 and Figure 8-11 show the routing for CK and ADDR_CTRL, respectively, for four DDR3 devices mirrored in a two-pair configuration.
