Molecular memory from Nanochip
San Jose Business Journal talks about Nanochip, a company that’s developing molecular-scale memory:
Nanochip has developed prototype arrays of atomic-force probes, tiny instruments used to read and write information at the molecular level. These arrays can record up to one trillion bits of data — known as a terabit — in a single square inch. That’s the storage density that magnetic hard disk drive makers hope to achieve by 2010. It’s roughly equivalent to putting the contents of 25 DVDs on a chip the size of a postage stamp.
The story also mentions Millipede project from IBM, where scientists are trying to build nano-scale memory that relies on micromechanical components.
