“Samsung has become the first to begin mass producing 16 gigabit (Gb) NAND flash, the highest capacity memory chip now available. The company said it will fabricate the devices in 51 nanometers (nm), the finest process technology to be used in memory mass production to date.”

“Samsung’s 51nm NAND flash chips can be produced 60 percent more efficiently than those produced with 60nm process technology. Samsung achieved this new migration milestone just eight months after announcing production of its 60nm 8Gb NAND flash last August.”

“Inside the iPod Nano are memory chips from Samsung and Toshiba. Samsung, the biggest producer of NAND and DRAM flash memory chips in the world, uses semiconductor manufacturing methods with precision below 100 nanometers. This precision, in part, is what enables the iPod Nano's 4 GB NAND flash memory.”
