Intel and Micron on Thursdaysaid they had developed the world's first 20 nanometer NAND flash memory in what could be a leap for mobile device storage. An 8GB example chip is 30 to 40 percent smaller than the current-best 25nm process and is just over 0.18 inches squared. The two companies expected the 20nm design to be just as fast as with 25nm but to be noticeably cheaper to make for equivalent features, since it could produce 50 percent more gigabytes of storage than they do today.
