8.13.3.14.2 Two DDR3 Devices

Two DDR3 devices are supported on the DDR EMIF consisting of two x8 DDR3 devices arranged as one

bank (CS), 16 bits wide, or two x16 DDR3 devices arranged as one bank (CS), 32 bits wide. These two

devices may be mounted on a single side of the PCB, or may be mirrored in a pair to save board space at

a cost of increased routing complexity and parts on the backside of the PCB.

Figure 8-66 shows the topology of the CK net classes and Figure 8-67 shows the topology for the

corresponding ADDR_CTRL net classes.
