Founding Story
Hyundai Group founder Chung Ju-yung set up Hyundai Electronics in 1983 to enter semiconductors. After the 1997 Asian financial crisis, a government-led restructuring merged it with LG Semicon in 1999. The business was spun off from Hyundai as Hynix Semiconductor in 2001 and spent a decade under creditor control. SK Telecom bought a controlling stake in 2012, renamed it SK hynix, and funded the R&D that later produced the first HBM chips in 2013.
Founders
Chung Ju-yung
Chung Ju-yung (1915-2001) founded Hyundai Electronics in 1983 as part of his massive industrial conglomerate. He pushed the company aggressively into the highly capital-intensive semiconductor business. The company eventually merged with LG Semiconductor in 1999 to form Hynix, which was later acquired by the SK Group in 2012, long after Chung's direct involvement ended. (Exact birth year remains publicly undisclosed).
