RAM can't do much without a CPU. (Besides the first type I mentioned requires "refresh" cycle to recharge the capacitors, and it "usually" requires an another IC's.) I'll vote for the voltage regulator. I don't own M6, but I suspect it is rather a simple bridge circuit - but "blinking" part might require some complexities since it requires some sort of oscillation, but a single transistor circuit would do this oscillation job well. I am amazed that they changed the IC alone because a Japanese camera manufacture just would pull off the flexi-board and stick the new one in. Electronic equipments usually are designed that way.
