(Yicai Global) March 14 -- Samsung Electronics Co., the world's largest chipmaker, will start construction on a new NAND flash memory production line at its plant in Xi'an, capital of China's central Shaanxi province, as part of efforts to keep up with expected semiconductor demand in the medium- to long-term, Yonhap News Agency reported.

The Korean electronics heavyweight first announced plans for extra capacity last August and will invest USD7 billion in the expansion over three years.

Samsung also broke ground late last month on a project to expand extreme ultraviolet processor chip production at the Hwaseong factory in its native South Korea.
