Not that you'd want memory chips running through your blood stream in the first place, but two scientists in California have made a memory chip that measures about one-2,000th of an inch on the side. In other words, it's roughly the size of a white blood cell (those green dots surrounding the chip on the image to your right). Storage-wise, the chip doesn't hold much (160,000 bits), but it shows just how small memory chips can get in the future, which makes that microSD card seem like Rosie O'Donnell in comparison.
