A report published in the journal Nature Nanotechnology suggests that 500,000 gigabytes of memory could be squeezed onto one square inch of flexible plastics. Prof Lee Cronin and Dr Malcolm Kadodwala chemists at Glasgow University "have developed a molecular switch which means that data storage can be dramatically increased without the need to increase the size of microchips" according to this article at Telegraph.co.uk. No mention is made of the potential for bringing this technology to market, seems as though it is all theoretical at the moment. Cool though if they can make it work!
