How does it work? This explains somewhat:
http://informationweek.com/story/showArticle.jhtml?articleID=59300089
"…a quantum effect called "tunneling" can impair transistors by causing
electrons to leak through their gates, throwing off the distinctions
between 0's and 1's that computers rely on to perform their logic.
HP's approach, on the other hand, exploits the tunneling effect. Its
crossbar latch consists of three criss-crossing platinum and titanium
wires joined by a layer of electrically switchable molecules of stearic
acid (a fatty acid that also appears in soap, candles, and chocolate)
measuring 2.8 nanometers thick. Traditional computers use semiconductor
properties to form the "latch" that preserves the output of a
computation for later use."
I need a more detailed and understandable explanation.
