Dutch scientists have developed a rewritable memory that stores information in the positions of individual chlorine atoms on a copper service, greatly aiding the quest to develop storage devices that can pack evermore information into a smaller space.
The 1 kilobyte device has an information storage density that is two to three orders of magnitude beyond current hard disk or flash technology. With each bit of data represented by the position of a single chlorine atom, the team was able to reach a density of 500 Terabits per square inch.
