None of the DDR2 and onwards memories have anywhere near enough bandwidth to meet refresh frequency on each bit by you even just reading it in a loop. The refresh that we do is run in parallel on the memory arrays inside the RAM chips completely bypassing any of the related IO machinery. |

I'm not saying that it's easy or cheap or worthwhile (I'd rather guess it's not in most cases), but I don't see why it couldn't be done.
