Chipmakers Intel and Micron said Tuesday they've created a hyperfast memory chip, up to 1,000 times faster than standard NAND Flash memory. Intel and Micron say they've been working more than a decade on their new, "3D XPoint" chip, which is based on a new, three-dimensional structure and a different set of materials than standard memory chips. The new chip doesn't use transistors, which are the standard on/off switches in microprocessors and nearly every other category of computer chip.
