SK Hynix is embarking on a long-term production network strategy to meet the growing demand for artificial intelligence (AI) memory, connecting Yongin, Cheongju, and the Southwest region of South Korea. The company aims to accelerate the Yongin semiconductor cluster timeline and establish Cheongju as a hub for AI memory while creating a new production cluster in the Southwest region.
On June 29, SK Hynix announced a comprehensive investment strategy totaling 1.1 trillion won ($1.1 trillion), with 600 trillion won allocated for Yongin, 100 trillion won for Cheongju, and 400 trillion won for the Southwest region. This initiative is designed to secure large-scale production bases in anticipation of a surge in demand for high-performance memory, including High Bandwidth Memory (HBM), driven by the expansion of AI data centers.
Yongin is set to become a key production base for SK Hynix. Originally scheduled for completion in 2045, the Yongin semiconductor cluster's timeline has been moved up by 12 years, with the goal of finishing the construction of its fourth fab by 2033. Following this, investments in production facilities and equipment will be rolled out gradually.
Cheongju will be developed into a comprehensive production hub for AI memory. SK Hynix plans to invest 100 trillion won in building a new NAND fab and acquiring production equipment in Cheongju. The company will also enhance its advanced packaging capabilities for HBM in Cheongju, integrating NAND, HBM, and advanced packaging to meet the demands of AI data centers.
The Southwest region is emerging as a new production base. SK Hynix intends to invest 400 trillion won in stages to establish a new production site following its facilities in Icheon, Cheongju, and Yongin. The Southwest cluster will focus on memory front-end production, with site acquisition, fab construction, and equipment installation occurring sequentially.
This investment strategy aims to expand production capacity rather than replace existing facilities. Icheon will continue to serve as SK Hynix's headquarters and a center for research and development and advanced processes. Yongin, Cheongju, and the Southwest region will function as production hubs to address the increasing demand for memory.
The rising demand for HBM also underpins this investment. HBM requires more wafers and advanced packaging processes than standard DRAM, meaning that even for the same capacity, production resources are more heavily utilized. As the share of AI memory grows, securing sufficient production capacity in advance becomes a competitive advantage.
SK Hynix plans to implement this investment gradually over the long term, aligning with demand visibility rather than injecting all funds at once. The company will base its funding on cash flow generated from operations while adjusting the scale and timing of procurement according to market conditions and investment principles. Various funding options, including collaborations with global partners, are also being explored.
Industry analysts view this strategy as a move by SK Hynix to connect its HBM leadership with long-term production capabilities. The AI memory market continues to face supply shortages, and the lengthy timeline from site selection to operational readiness for new fabs necessitates proactive measures.
