DDR2 SDRAM interleving??

Hi everyone,

I am using Cyclone III dev. board. I am trying to design a DDR2 SDRAM controller using SOPC builder. I need to increase the bandwidth and want to do memory interleaving, but have no idea how to do that. Is there a setting in SOPC DDR2 wizard to do interleaving, or do I have to write it myself?

    Hi,

    Could you find a way to do bank interleaving? If yes, please share as I am also struggling with it. Actually I could do it for read transfers and got a seamless consecutive read transactions on different banks. But, write transfers are with bubble of 4-5 clocks when I change the bank.

    Best regards.
