Transistors to go the way of vacuum tubes?
"If we're going to extend Moore's Law for another several decades, we've got to have an alternative strategy," said Phil Kuekes, one of the paper's authors at H-P Labs. "This is the final piece of the puzzle in what H-P has been putting together as such a strategy."
The smallest features of today's silicon-based transistors are about 90 nanometers long, a nanometer being roughly one hundred-thousandth the width of a human hair. The crossbar latch, by comparison, can work in a space of about 2 to 3 nanometers.
