Samsung today announced the industry’s first production of 20 nanometer (nm) class NAND chips for use in Secure Digital (SD) memory cards and embedded memory solutions. Samsung’s 20nm-class MLC NAND has a 50 percent higher productivity level than 30nm-class MLC NAND. The write performance of a 20nm-class-based, eight gigabyte (GB) and higher density, SD card is 30 percent faster than the 30nm-class NAND and it delivers a speed-class rating of 10 (read speed of 20MB/s, write speed of 10MB/s). By applying cutting-edge process, design and controller technology, Samsung also has secured reliability levels comparable to 30nm-class NAND.


Samsung’s timely introduction of its high-performance premium NAND will better support the growing memory requirements of high-density smartphones, high-end IT applications and high-performance memory cards. Memory cards based in the 20nm-class will be available from 4GB through 64GB densities.
