SK hynix accelerates Korea AI memory expansion with 1.1 quadrillion won plan - CHOSUNBIZ - Chosunbiz

SK Hynix has unveiled a mid-to-long-term investment plan totaling 1.1 quadrillion won (approximately 580 billion RMB) to meet the growing demand for artificial intelligence (AI) memory. The initiative... Read original →

SK hynix’s 1.1 quadrillion KRW AI memory expansion is less about capacity and more a forced infrastructure upgrade driven by HBM and advanced NAND process complexity. Technically, TSV and hybrid bonding will intensify cleanroom and tool density demands, benefiting domestic equipment makers like SEMES. Geopolitically, while concentrating production in Korea mitigates U.S. export control exposure, it inflates per-wafer costs and reduces flexibility with packaging partners in Taiwan, China. Competitively, Micron is fast-tracking HBM3E in Arizona, and Samsung may counter by scaling GDDR7 output at its Xi’an fab to retain hyperscaler clients. Over the next 12–24 months, this move will stratify the AI memory market: only vendors capable of HBM4+ will access top-tier AI chipmakers, squeezing out smaller players and accelerating industry consolidation.
