Figure 7-51 shows the CK routing for three DDR3 devices placed on the same side of the PCB. Figure 7-52 shows the corresponding ADDR_CTRL routing.
To save PCB space, the two DDR3 memories may be mounted as one mirrored pair at a cost of increased routing and assembly complexity. Figure 7-53 and Figure 7-54 show the routing for CK and ADDR_CTRL, respectively, for two DDR3 devices mirrored in a pair configuration.
