4.4.2

DRAM and SDRAM Configurations

Table 4.4.2 shows the various combinations of DRAM and SDRAM chips that are supported. Bank 1

and Bank 0 are independently programmable so each can contain any of the combinations. The only

restriction is that Bank 1 cannot contain SDRAM if Bank 0 contains DRAM.
