Figure 7-51. ADDR_CTRL Routing for Two Single-Side DDR3 Devices
To save PCB space, the two DDR3 memories may be mounted as a mirrored pair at a cost of increased
routing and assembly complexity. Figure 7-52 and Figure 7-53 show the routing for CK and ADDR_CTRL,
respectively, for two DDR3 devices mirrored in a single-pair configuration.
