Samsung announces production of Worlds First Higher-performing 20nm-class NAND Flash Memory
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.
