Microsoft invests in AFM-based memory chip

Janet Rae-Dupree of the San Jose Business Journal reports that Microsoft is an investor in Nanochip, which uses AFM arrays to read and write chips with up to a terabit per square inch. They're not at the atomic level yet, but wait: "While the term 'atomic force' may make it sound like the data is being stored by manipulating individual atoms, the truth is that each individual bit is made up of hundreds of molecules, [CEO Gordon Knight] says. 'That's the beauty of this technology,' he says. 'It does have legs. We can see it getting finer and finer in the future with better tips and better media.' " Credit KurzweilAI.net
