Scientists create world's densest memory circuit

Researchers in California said they have created the world's densest memory circuit, one that's about 100 times denser than today's standard memory circuits, while remaining as small as a human white blood cell.

Scientists from the California Institute of Technology and the University of California, Los Angeles, reported the development in Thursday's issue of the journal Nature.

The circuit has 160,000 bits of capacity, compared with previous generations of molecular circuits that were demonstrated at 64 bits.

But researchers point to the circuit's density as the real breakthrough: 100 billion bits per square centimeter, which the researchers said is about 100 times more tightly packed than current memory circuits.
