SK Hynix Was Already Planning To Double Memory Capacity Before Jensen Huang Scribbled ‘Please Make More’ On A Wafer - Wccftech

SK Hynix’s pre-emptive plan to double memory capacity wasn’t a reaction to Huang’s scribble—it was a calculated bet on AI-driven HBM demand. Technically, this accelerates EUV and hybrid bonding adoption upstream while forcing GPU designs downstream to prioritize bandwidth density. Geopolitically, concentrating expansion in Korea avoids U.S.-China export controls but heightens supply chain fragility amid Taiwan Strait tensions. Samsung will inevitably match pace, while Micron leverages CHIPS Act subsidies to scale Arizona-based HBM lines, cementing a Korea-U.S. duopoly. Over the next 18 months, HBM5 standardization and CoWoS packaging bottlenecks will exacerbate supply-demand imbalances. SK Hynix’s head start may secure supernormal margins through 2027—but aggressive capex risks triggering a cyclical glut if AI deployment slows.
