HONEYCOMB MEMORY
IBM says it may have found a way to dramatically increase the density of memory chips. This limit is determined by the wavelength of light used to carve the logic gates on chips. Now researchers from IBM’s T. J. Watson Research Center in New York say it is possible to bypass this limitation by exploiting the ability of certain materials to self-organise into a regular molecular pattern.
Announcing their results at an electronics meeting in Washington DC last week, the team said they started out with a mixture of poly(methyl methacrylate) (PMMA) and polystyrene. When heated, the polymers…
