Computer components shrinking faster than predicted - tech - 20 February 2009 - New Scientist

The New Scientist article summarizes two recent discoveries. The first is a novel form of magnetic memory that could store 10 terabytes per square inch, a significant increase over the current limit of 0.5 Terabytes per square inch. The researchers believe this approach could soon lead to memories with densities approaching 100 Terabytes per square inch. The second discovery is a new form of transistor based on perovskite, rather than silicon, that can be as small as 2 nanometers, far smaller than the 45 nanometres of contemporary transistors. The circuits can also be redrawn up to 100 times, making the circuit somewhat hardware rewritable.
