Memory Configuration
► Bank Interleaving
Interleaving allows banks of SDRAM to alternate their refresh and access cycles. One bank
will undergo its refresh cycle while another is being accessed. This improves memory perfor-
mance by masking the refresh cycles of each memory bank.
However, bank interleaving only works if the addresses requested consecutively are not in the
same bank.
► Channel Interleaving
Dual channel (Interleaved) mode offers the highest throughput for real world applications. Dual
channel mode is enabled when the installed memory capacities of both DIMM channels are
equal. If different speed DIMMs are used between channels, the slowest memory timing will be
used.
To achieve Dual Channel Interleaving mode, the following conditions must be met:
Matched DIMM configuration in each channel
Same Density (128MB, 256MB, 512MB, etc.)
Matched in both Channel 0 and Channel 1 memory channel
► DCT Unganged Mode
DCT stands for DRAM Controller.
Ganged refers to the use of both DRAM controllers within a memory controller acting in con-
cert to access memory. For a description of ganged (128-bit DRAM data width) and unganged
(64-bit DRAM data width) DRAM modes :
Ganged channels (DDR3) :
■ DCT channels A and B can be ganged as a single logical 128-bit DIMM.
■ Offers highest DDR3 bandwidth.
■ Requires both DIMMs in a logical pair to have identical size and timing parameters, both
DCTs programmed identically.
