Notice that memory-space accesses (0x00000000 - 0x03EFFFFF) that hit addresses where there is no RDRAM chip mapped will result in a sort of "no-operation" behavior: reads will return zero, and writes will be ignored. For instance, in a N64 with 8 MiB (through expansion paks), reads at the 9 MiB are not a mirror of the reads at the first MiB: they just return zero because no chips in the RAMBUS will reply to those requests. |
