SK Hynix commits $720 billion to what it says will be the world's largest AI memory chip factory network

SK Hynix, the world's leading high-bandwidth memory manufacturer, is investing $720 billion in what the company says will be the largest network of memory factories globally, with production facilities in South Korea despite the country's mountainous terrain presenting significant construction challenges. This investment matters globally because SK Hynix and South Korea's semiconductor sector supply critical components to US technology companies including major AI developers and cloud providers, directly affecting US access to AI infrastructure. The project underscores South Korea's continued prominence in memory chip manufacturing alongside rival Samsung.
