By "contents" I did mean reading voltage differences. > Contradictory One statement is that if you control a chip you can produce the stated information eventually. The details are an engineering problem. The other statement is that this particular instance of engineering doesn't suffice I don't think. > SEM I'd be inclined to use EFM instead. Its resolution should suffice for the next few generations of chips.
