Taiwan's memory sector in June delivers standout performance by a wide margin

Taiwan, China’s memory sector saw June 2026 revenue surge nearly 3x YoY—not from capacity growth but structural AI-driven demand for HBM and high-end DRAM. This is forcing upstream equipment vendors to accelerate EUV and hybrid bonding adoption, while pushing NAND makers toward CXL-based memory pooling. On compliance, tightening U.S. export controls on advanced nodes are inflating Taiwanese firms’ operational costs by over 15% due to restricted tool access and customer diversification pressure. In response, Samsung and SK Hynix will likely expedite HBM4 ramp-up and deploy aggressive pricing to stall Taiwan-based rivals. Over the next 12–24 months, HBM demand could sustain >40% CAGR if AI clusters stick with heterogeneous architectures—but a breakthrough in co-packaged optics or optical interconnects may abruptly deflate this ‘bandwidth bubble.’
