SK hynix, Inc.

Company Background

SK Hynix is one of world's largest manufacturers of semiconductors.

The company began as Hyundai Electronics Industries, established in 1983 by South Korea's Hyundai group. In 1999, the company acquired LG Semiconductor from South Korea's LG group. It changed its name to Hynix Semiconductor in 2001. The company came under the supervision of financial institutions in 2001 amid balance sheet troubles and restructured. In 2011, the company came under the umbrella of leading South Korean mobile carrier SK Telecom, a unit under SK Holdings. It changed its name to SK Hynix in 2012.

SK Holdings also operates businesses in energy and other sectors. The group's Chairman Chey Tae-won also serves part-time as Chairman of SK Hynix. SK Hynix's earnings have rapidly grown thanks to its aggressive capital investment, after becoming a member of the country's major conglomerate.

Japanese electronics maker Toshiba filed a damages suit against its business partner SK Hynix over the leak of NAND flash memory data, which has been settled. The two companies continued to work together on a next-generation memory chip even during the lawsuit.

SK Hynix operates plants in South Korea's Icheon, Gyeonggi Province; Cheongju, Chungcheongbuk Province; and China's Wuxi, Jiangsu Province.

Business Summary

SK hynix, Inc. engages in the manufacture and sale of semiconductor products. Its products include dynamic random access memory, flash memory, complementary metal oxide semiconductor image sensor, and others. The company was founded on October 15, 1949 and is headquartered in Icheon, South Korea.
