Popular Science reports that HP has discovered the potential “God Particle” of electronics. The article explains that:
The device, a nanoscale component called a “memristor,” requires no power to retain data, which it can store more densely than a hard drive and access about as fast as a computer’s RAM memory—potentially allowing it to replace both components in the future.

The memristor was theorized in the early seventies by an electrical engineer named Leon Chua, but it took decades before anyone could prove it exists.
The Slashdot thread on the subject is also interesting…
