IBM's new phase-change memory alloy, also called GS for the two elements -- germanium and antimony -- that make it up, can quickly move between amorphous and crystalline states, reproducing the ones and zeroes used to store the world's electronic data. The GS alloy is faster than current flash memory by a factor of 500, uses half the power, and, like flash, retains its data when the power is off.

weighs in at a mere 3 x 20 nanometers. Like flash, it retains its data when the power is off -- a memory quality called "nonvolatile." But unlike flash, it works as quickly as RAM, meaning that IBM's alloy might one day make its way into computers and processors as an ultrafast, ultracool, ultrasmall way to store data.
