Ian Lamont writes "An Arizona State University researcher named Michael Kozicki claims that nanotechnology will replace disk drives in ten years. The article mentions three approaches: Nanowires (which replace electrons/capacitors), multiple memory layers on silicon (instead of a single layer), and a method that stores multiple pieces of information in the same space: 'Traditionally, each cell holds one bit of information. However, instead of storing simply a 0 or a 1, that cell could hold a 00 or a 01. Kozicki said the ability to double capacity that way — without increasing the number of cells — has already been proven. Now researchers are working to see how many pieces of data can be held by a single cell.'"
