HP shows off tiny wireless memory chip

A chip the size of a grain of rice that can store 100 pages of text and swaps data via wireless has been developed by Hewlett-Packard. The chip could be used to ensure drugs have not been counterfeited, on patient wristbands in hospitals or to add sounds or video to postcards, said HP. The chip, developed by the Memory Spot research team at HP, is 2-4mm square and current versions can hold up to 512 kilobytes of data. Do not hold your breath for it, as it is still around 2 years away from being a finished product.
