Samsung Electronics has been the world's-largest memory chip maker since 1993. In 2009 it started mass-producing 30 nm-class NAND flash memories. 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.
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. Gartner analysts said in their report, "Samsung cemented its leading position by taking a 35-percent market share. All the other suppliers had minimal change in their shares." The company took the top slot in the ranking, followed by Hynix, Elpida, and Micron, said Gartner.
Another hitherto not-well-publicized area where the company had significant business in for years is the foundry segment. It had begun investment in the foundry business sem service since 2006 and now positioned it as one of the strategic pillars for semiconductor growth.
In 2010, market researcher IC Insights predicted that Samsung would become the world's-biggest semiconductor chip supplier by 2014, surpassing Intel. For the ten-year period from 1999 to 2009, Samsung's compound annual growth rate in semiconductor revenues has been 13.5 percent, compared with 3.4 percent for Intel.
