Samsung plans to build a new $4 billion flash memory chip plant in China, its second overseas chip manufacturing site.
Samsung, the world's top maker of memory chips and flat screens, is planning the move as a boom in smartphones and tablet computers is set to fuel the $22 billion chip industry's growth next year.
Samsung is also planning to build a flat-screen production base in China, reflecting the growing importance of the Chinese market.
The new line "will enable us to meet fast growing demand from our customers and at the same time strengthen our overall competitiveness in the memory industry," the president of Samsung's memory business, Jun Dong-soo, said.
The company said it hoped to have the new line operating by 2013.
The global NAND memory chip market is seen growing 20 percent next year to $26 billion, according to chip price tracker DRAMeXchange.
"China is expected to overtake the United States as the top market for electronics products with its income levels growing," said Kim Young-chan, an analyst at Shinhan Investment.
Samsung, whose flash chips are used in Apple's iPhone and iPad tablet, said it had yet to decide the exact amount of investment or a site for the plant.
Kim estimated Samsung would invest between 4 trillion won ($3.5 billion) and 5 trillion won to build the new facility.
The move is widely seen aimed at catering to Chinese manufacturers such as Huawei Technologies and ZTE, which have been steadily raising their global smartphone and tablet market share.
Flash memory stores data even when power is turned off and is widely used in devices such as smartphones, tablets, digital music players and portable USB memory devices.
It is also increasingly replacing hard drives as a main memory storage in laptops because it has much faster boot times.
The new production line would use cutting-edge 20-nanometer-class processing technology.
Samsung is aggressively boosting production of flash chips. In September, it started mass production at a new $10 billion chip line in South Korea.
Samsung said it had filed an application for the foreign production base with the South Korean government, which requires firms to make such requests for fear of leakages of the country's prized high technology.
Samsung is the world's biggest NAND flash memory maker with around 40 per cent of the market.
It competes with Japan's Toshiba, Hynix Semiconductor of Korea and Micron Technology of the United States.
Samsung's sole foreign chip plant in Austin, Texas, has also raised production to full capacity ahead of schedule for logic semiconductors, such as the processing chips used to power mobile devices, after a $3.6 billion investment, it said in a separate statement.
