Seoul, Jan. 2, 2026 — Samsung Electronics said its next-generation HBM4 high-bandwidth memory chips had received positive customer feedback, showing the company is working to close the gap with SK Hynix in the AI memory market. As demand for AI servers continues to rise worldwide, HBM has become one of the most critical products in the semiconductor industry.
HBM chips are widely used in AI training and inference systems, providing high-speed data transfer for GPUs and specialized AI processors. Growing memory bandwidth requirements for large models have made HBM a core bottleneck in the AI supply chain.
The global HBM market is currently led by SK Hynix, Samsung and Micron. Samsung’s acceleration of HBM4 supply reflects intensifying competition among memory chipmakers to serve the AI data center market.
Analysts say AI chip competition does not belong only to GPU makers. Companies that can provide faster, more stable and more energy-efficient high-bandwidth memory will occupy a more important position in the expansion of AI infrastructure.
