Memory Chips: How Small Can They Go?

By Dick Weisinger

Peter Lee, a vice-president at Microsoft Research, said that “there’s a law about Moore’s law: The number of people predicting the death of Moore’s law doubles every two years.”

How small can we go?  Scientists had thought that they’re hitting final barriers on the limits to how small computer chips can be miniaturized, until new methods are discovered. Scientists are now using nanotechnology to hit new levels of miniaturization.

For example, researchers at the University of Alberta have come up with a technique to create computer memory at the atomic  that is 1000 times smaller than current methods.  They’re able to position individual atoms and create a stable configuration that persists even at above temperatures.

Roshan Achal, a PhD student in Department of Physics who is working on the technique, said that “essentially, you can take all 45 million songs on iTunes and store them on the surface of one quarter. Five years ago, this wasn’t even something we thought possible.”
