As I said: 2^64 = 18446744073709551616. That's how much RAM can be
directly addressed using 64-bit address registers. Compare this to
roughly 10^23 silicon atoms in a large die like a CPU or RAM
chip. That is the bulk silicon, only the surface of which is used, so
more realistically, only 10^17 silicon atoms are actually involved in
the electronic device at all. You would have multiple bits per silicon
atom -- that just isn't going to happen.
