IBM's Phase Change Memory stores three bits per cell

IBM has developed a prototype PCM — Phase Change Memomory — chip capable of storing three different values per cell instead of the normal 2. They also developed a new control mechanism capable of dealing with drift (which they say the new type of PCM chip does not experience).

I, for one, welcome our new ternary overlords.

So essentially is this a memory increase from 2-bits to 8-bits per-cell that's still going to be binary, or does that mean we'll be moving to octodecimal data?

I think it's a positive change in either case.

Note, I didn't RTFA, yet.
