Samsung Electronics ships faster HBM4E chip samples to customers; shares jump - WTVB

Samsung Electronics announced on May 29 that it has begun shipping samples of its latest high-bandwidth memory (HBM) chip, the HBM4E, to customers, gaining a competitive edge in the AI data center mem... Read original →

Samsung’s early HBM4E sampling shifts it from a laggard to a pace-setter in AI memory. By co-optimizing its 1c DRAM stack with a 4nm logic base die, it delivers >20% bandwidth gains, compelling NVIDIA and AMD to reassess supply chain diversification. This directly pressures SK Hynix—currently holding over 70% HBM market share—to accelerate HBM4 ramp, likely at the cost of yield stability. Geopolitically, while U.S. export controls on advanced memory remain pending, Samsung’s Anthropic partnership bolsters its ‘trusted vendor’ status, preemptively mitigating compliance risk. Over the next 18 months, HBM will dominate AI server BOM volatility. Leveraging its IDM model and EUV capacity, Samsung is positioned to bundle memory and logic offerings—capitalizing on TSMC’s foundry constraints—to capture more AI infrastructure mandates.
