I should let Andy speak for himself, but, I believe the answer is no --
earlier in the thread something made me think you were confusing RAM with
memory on the SD card -- RAM is not on the SD card, it is "closer" to the CPU,
on or near the motherboard. (I don't know whether an SOC (System on a Chip)
includes the RAM on the chip -- if not, it is much closer, physically and
electrically to the CPU than the SD card.
