SK Hynix was able to achieve record-high earnings in 2013 powered by rising semiconductor chip prices. Full-year sales amounted to W14.17 trillion, while operating profit came in at W3.38 trillion (US$1=W1,080).
Sales were up 39 percent compared to 2012, while operating profit shifted to the black from an operating loss of W227 billion over the same period.
DRAM memory chip prices rose from 80 cents in December of 2012 to US$1.97 in December of 2013.
In the early 2000s, there were more than 10 semiconductor chipmakers in the world, but that number has now shrunk to just three (Samsung Electronics, Micron and SK Hynix) leading to a more stable market structure.
SK Hynix said sales of other products such as NAND flash chips and CMOS Image Sensors also rose. Doh Hyun-woo at Mirae Asset Securities said, "Demand for DRAM chips for smartphones and other devices will continue to increase, while production capacity will recover as well, translating into sustained growth momentum for SK Hynix this year."
