wily: No idea. It looks doable soon but cost will be the deciding factor if it makes as a general DRAM or just as a specialty item for where speed and permanence are both needed- ie digital cameras, MP3 players etc. FWIW IBM went from copper chip mockups to actual product (powerpc chips now in Macs) in about a year. As the article mentions IBM already has a big effort in this area for disks. IF THIS WORKS a big loser is Rambus. IBM has not licensed the copper technology to anybody other than MOT (they are partners in powerpc) as far as I know. Its idle speculation, at this point, as to whether they would license the tunneling technology. The Japanese are also studying this technology. IBM already has demos of conventional design, 0.15 micron, on copper DRAM running in the neighborhood of 800 MHz--see an earlier post for link.
