Submission + - Phase change memory points to future of storage (scienceblog.com)

An anonymous reader writes: A UC San Diego team is about to demonstrate a solid state storage device that it says provides performance thousands of times faster than a conventional hard drive and up to seven times faster than current state-of-the-art solid-state drives (SSDs). The drive uses first-of-its kind, phase-change memory, which stores data in the crystal structure of a metal alloy called a chalcogenide. To store data, the PCM memory chips switch the alloy between a crystalline and amorphous state based on the application of heat through an electrical current. To read the data, the chips use a smaller current to determine which state the chalcogenide is in.

When someone uses the phrase "exonerate the innocent", it just says that air travelers are presumed to be guilty of terrorist activities and have to prove themselves innocent. Not exactly an American ideal, but American ideals are all too readily sacrificed on the altar of security theater.
