Figure 7-45. ADDR_CTRL Routing for Four Single-Side DDR3 Devices
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 7-46 and Figure 7-47 show the routing for CK and
ADDR_CTRL, respectively, for four DDR3 devices mirrored in a two-pair configuration.
