Samsung Electronics Allocates Half HBM Production to HBM4 - 조선일보

Samsung Electronics is allocating half of its high-bandwidth memory (HBM) production capacity to the sixth-generation HBM4, aiming to regain market share. Following the first shipment of HBM4 in Febru... Read original →

Samsung’s reallocation of half its HBM capacity to HBM4 marks a strategic bid for AI hardware architecture leadership, not just a generational upgrade. Technically, this accelerates co-optimization between advanced packaging (e.g., X-Cube) and 3nm EUV logic processes, pushing ASIC-memory stacking toward monolithic integration and compressing NVIDIA’s Rubin validation timeline. On compliance, tighter U.S. export controls on advanced memory favor Samsung’s localized supply chain over rivals reliant on Taiwan, China-based OSATs, enhancing supply resilience. SK Hynix, while dominant in HBM3E for Blackwell, risks irreversible share erosion if it misses HBM4 volume ramp by late 2026. Over the next 12–24 months, custom AI accelerators from cloud giants will demand tailored HBM solutions—Samsung’s foundry-packaging-memory vertical integration positions it to evolve from secondary supplier to architectural co-definer.
