Imagine a memory chip roughly the size of a white blood cell. Scientists have made it a reality - they have created a miniscule memory chip about one-2000th of an inch on a side. Although the chip is modest in capacity (with 160,000 bits of information), the bits are crammed together so tightly that it is the densest ever made. The scientists, led by James R. Heath of the California Institute of Technology, reported their findings in the journal Nature.
The density of bits on the chip - about 100 billion per sq. cm - is about 40 times that of current memory chips. Improvements to the technique could increase the density by a factor of ‘10,’ said Heath.
The wires used in the chip have about the same width as proteins and that could make possible tiny circuits that could detect cancer or other diseases.
