- Bank Interleaving:
Depending on your SDRAM module structure, the 4-Way setting can offer the best performance.
If you choose the wrong setting, the computer system will not run in a stable manner. For
detailed information on your SDRAM module, please ask your SDRAM module manufacturer.
- Burst Length
DDR SDRAM modules provide a Burst mode that means an auto precharge function for
programmable READ or WRITE burst lengths of 2, 4 or 8 locations.
This means that if we set burst length to 8, the address bus will access 8 bytes each cycle to
precharge, etc.
