DDR/SDRAM Pin swapping

[jonpry]

Hi,

I am designing an embedded system which uses DDR memory attached to an OMAP3 processor. I'm aware that bits can be swapped within a byte, but would be the effect of swapping the address bits around. I realize the initialization commands would have to be changed, and maybe some address bits can not be changed as it would change the organization of the memory. This would really help out my project if it were possible. Any experience?

Thanks,

Jon Pry

you can swap any pin within a byte! don't be worry! i do that for our tms320dm6446 and s5pv310 project, no problem!
