Samsung, the world's largest memory chip maker, runs a chip manufacturing plant in the Chinese city of Xian, which accounts for some 40 percent of its global NAND flash production. In Suzhou, the chipmaker runs a semiconductor packaging factory. Its smaller rival SK hynix currently operates multiple plants in China, including one in the eastern city of Wuxi, where it manufactures about half of its global DRAM chips. –IANS na/
