Samsung Allocates Half HBM Capacity to HBM4 - 조선일보

Samsung Electronics has allocated half of its high-bandwidth memory (HBM) production capacity to the sixth-generation HBM4, signaling a strategic push to regain market share after a recent first shipm... Read original →

Samsung’s aggressive HBM4 pivot isn’t just a product refresh—it’s a strategic bid to capture AI hardware ecosystem control. Technically, HBM4 demands 3nm EUV and advanced TSV packaging, forcing upstream equipment and materials suppliers to accelerate upgrades while pushing ASIC designs toward higher bandwidth. On compliance, tightening U.S. export controls on advanced memory expose Samsung to supply chain fragmentation if overly reliant on North American cloud clients, necessitating redundant capacity in Korea and Vietnam. SK Hynix can temporarily anchor on NVIDIA’s Blackwell-driven HBM3E demand, but delayed HBM4 ramp risks irreversible market share erosion once Rubin scales in 2026. Over the next 18 months, HBM4 will become the performance inflection point for AI accelerators—Samsung’s bold move mirrors its historic DRAM playbook: disrupt competitors through aggressive node transitions and ultimately redefine the high-end memory hierarchy.
