Samsung

For more than 20 years since 1993, Samsung has kept the title of the world’s largest memory chip maker. In 2009, it began a strategy of “Green Memory” by which it increased the global DRAM market share to 33 percent. It also started mass-producing 30 nm-class NAND flash memories in the same year whose world share rose as high as 42 percent.[36] It succeeded in 2010 in mass-producing 30 nm-class DRAMs and 20 nm-class NAND flashes, both of which were the first time in the world.[37] According to market research firm Gartner, during the second quarter of 2010 Samsung Electronics took the top position in the DRAM segment due to brisk sales of the item on the world market.
