According to the popular science mag Nature, Caltech and the UCLA have come up with what they think is the densest memory circuit board in existence.
The 160-kilobit memory cell say has a bit density of 100 gigabits per square centimetre.
Caltech chemistry professor James Heath, who led the research said it would be ages before the technology ends up in a lap top. Heath thinks it is the sort of technology that Intel will be deploying in about 2020.
Manufacturers are stuck at how to extending miniaturisation of circuits beyond the year 2013 as they have not really worked out a way of defeating Moore's Law.
