Hi,

I am planning to do some pin swapping for Address line in DDR3. Can you provide any reference design(Schematics) and software code.

What are problems/disadvantage will come across on doing pin swapping.

T & R

    Hi Karthik,
     
    If you swap any of the address/control signals of the DDR3, the result will be that it simply will not function at all. The only signals that can be swapped are data bits within a byte. Also the two data bytes can be swapped, along with their corresponding DQM, DQS and DQSn signals.
     
    If you have any doubt better post part of the schematic here.
