Memory module population

5.1 Memory module population
Figure 5: Structure of the main memory in memory banks and memory modules
– The memory modules have to be based on x4 organized SDRAM and must
be populated in pairs
– Each pair must consist of identical memory modules (2-way Interleaved-
mode).
– The memory module capacity can differ for the various memory banks: e.g.
memory bank 0A/0B can be equipped with two 512-Mbyte memory
modules, and memory bank 1A/1B with two 1-Gbyte memory modules.
– Only single ranked modules are permitted.
The following table shows the required memory population sequence:
