Well, that's a description that fits most (all?) disk-based music players. The
question is only how much of the ram that is used for buffer and what else
there is in there. I would say that the addresses used in the firmware
indicates that there's code in at least parts of the ram.

I would assume that executing in ram is faster than from flash. Of course the
CF5249 also has 96KB internal ram.
