Scientists develop 100Gb/cm² memory cell
A team of scientists from the California Institute of Technology and the University of California, Los Angeles has developed a memory cell
(sub. required) that packs 160Kb of data in an area no bigger than a human white blood cell. The density is equivalent to 100Gb/cm², which would hypothetically allow memory manufacturers to squeeze 125GB of data in a memory chip the size of a postage stamp. What sets this particular cell apart is that it uses organic molecules to store binary information, allowing much higher densities than current silicon-based memories.
Of course, being an experimental prototype, the organic cell has some shortcomings, including only being able to have its contents changed ten times. Caltech chemistry professor James Heath said "[the cell is] the sort of device that Intel would contemplate making in the year 2020." However, he also told Nature, "It wouldn’t surprise me if we really did have to wait until 2020 to see molecular devices with this bit density actually being used."
