SK Hynix — Headquarters: Icheon, South Korea

NoteThe Wikipedia source explicitly states in the infobox at the beginning of the article: 'Headquarters: Icheon, South Korea'. This directly confirms the claim. The source also mentions in the Operations section that 'SK Hynix has production facilities in Icheon and Cheongju, South Korea', further corroborating the Icheon location as a major operational center.
