DDR Memory Controller
If a transaction request is issued to the DDR memory controller and the address does not lie within any of
the programmed address ranges for an enabled chip select, a memory select error is flagged.
Using a memory-polling algorithm at power-on reset or by querying the JEDEC serial presence detect
capability of memory modules, system firmware uses the memory-boundary registers to configure the
DDR memory controller to map the size of each bank in memory. The memory controller uses its bank
map to assert the appropriate MCSn signal for memory accesses according to the provided bank starting
and ending addresses. The memory banks are not required to be mapped to a contiguous address space.

Table 9-27
address presented at the memory controller signals MA[14:0] use MA[14] as the msb and MA[0] as the
lsb. Also, MA[10] is used as the auto-precharge bit in DDR1/DDR2 modes for reads and writes, so the
column address can never use MA[10].
