A Switch in Time - So reads the title of a News Feature (Nature 2007, 445, 362) by Philip Ball in the 25 January Issue of Nature where a Letter (Nature 2007, 445, 414) describes an array which is no bigger than a single white blood cell, yet it contains 160,000 memory cells - made up of around a couple of hundred bistable rotaxane molecules - each with an area of just under 300 nanometers square - some 40 times smaller than those in existing devices. This density of memory matches potentially the needs of the semiconductor industry some 13 years from now, i.e., in 2020. For more information, see the UCLA News report dated 24 January 2007. This development has also been featured in the Science Section of the New York Times!
