Dynamic memory? Not so much

A group of researchers found a way to retrieve memory in RAM from a computer: lower the temperature of the RAM chips. One method they used was compressed air. This isn't a real security threat to the merely mortal among us - I'm interested in it because it sounds like an incredibly fun project. Still they are handicapped by researcher-talk: "data written even momentarily to RAM persists for a non-trivial period of time." Here's all the dirt.
