The race for bigger and better memory continues apace, it seems. It was only a week or two ago that we caught wind of the work that scientists in Berkeley were doing with nanotubes and thousand-year-plus memory lifespans, and now it looks like a group of researchers in Japan have made some headway using an electron-beam direct-writing technique that utilizes semiconductor devices that can keep data intact for a thousand years, so long as humidity is kept at 2% or less. The prototype Digital Rosetta Stone, developed by Keio University, Kyoto University, and Sharp, has a storage capacity of 2.5TB and a max transmission speed of 150Mbps. Of course, there's no telling if or when this will become a reality, so if you want to ensure that your adolescent poetry lasts for the next thousand years, you'd better print out your MySpace blog and have it carved in granite.
