SK Hynix readies 375-layer NAND as US listing plan advances

SK Hynix’s push toward 375-layer NAND mass production and a U.S. listing reflects a strategic pivot under mounting pressure. Technically, this leap forces upgrades across the stack—from etch tools to ultra-pure chemicals—boosting demand for Tokyo Electron and Applied Materials. Regulatory risks loom large: U.S. CHIPS Act scrutiny may inflate capital costs and accelerate supply chain decoupling from China, raising operational friction. With Samsung showcasing 400-layer prototypes and Yangtze Memory rapidly scaling 232-layer tech, SK Hynix aims to lock in premium pricing in enterprise SSDs. Over the next 18 months, the industry’s 'layer race' will peak as physical limits bite; the real battleground will shift to HBM-CXL convergence, where stacking alone can no longer sustain margins.
