Seoul: Samsung Electronics has announced the production of 20 nanometer (nm) class NAND chips for use in Secure Digital (SD) memory cards and embedded memory solutions. Based on this technology, the introduction of 32 gigabit MLC NAND will expand the company's memory card solutions for smart phones, high-end IT applications and high-performance memory cards.
According to the company, the 20nm-class MLC NAND has a 50 percent higher productivity level than 30nm-class MLC NAND. Soo-In Cho, President, Memory Division, Samsung Electronics, said, "In just one year after initiating 30nm-class NAND production, Samsung has made available the next generation node 20nm-class NAND, which exceeds most customers requirements for high-performance, high-density NAND-based solutions."
Samsung Electronics first began producing 32Gb NAND with 30nm-class process technology in March 2009. Now it is shipping SD card samples to customers that are built with 20nm-class 32GB NAND and will expand production later this year. Memory cards based in the 20nm-class will be available from 4GB through 64GB densities, the company said.
