Figure 7-41 shows the required placement for the DDR2 devices. The dimensions for this figure are defined in Table 7-49. The placement does not restrict the side of the PCB on which the devices are mounted. The ultimate purpose of the placement is to limit the maximum trace lengths and allow for proper routing space. For single-memory DDR2 systems, the second DDR2 device is omitted from the placement.
