This is good for the development roadmap, and will create new opportunities for even denser circuits.

Scientists say they have made the world’s most dense computer memory circuit, capable of storing around 2000 words in a unit the size of a white blood cell.

The researchers, from the California Institute of Technology and the University of California, Los Angeles, publish their results today in the journal Nature.

But the chances of the device soon being used in a laptop is remote, says Caltech chemistry professor James Heath, who led the research.

The sad part is that it is already apparent that bandwidth issues will slow down next-generation devices more than the lack of sufficient or compact enough memory.
