Figure 6-19 shows the required placement for the device as well as the DDR2/mDDR devices. The dimensions for Figure 6-20 are defined in Table 6-28. The placement does not restrict the side of the PCB that the devices are mounted on. The ultimate purpose of the placement is to limit the maximum trace lengths and allow for proper routing space. For single-memory DDR2/mDDR systems, the second DDR2/mDDR device is omitted from the placement.
