Commentary: Memory boom driven by DRAM now, but HBM will decide future - digitimes

The semiconductor industry is experiencing a renewed growth cycle driven by artificial intelligence demand, with the memory market entering what many perceive as a long-awaited super-cycle. Samsung El... Read original →

The current DRAM rally is merely a short-term byproduct of AI demand; the real determinant of market leadership lies in HBM industrialization depth. Technologically, HBM’s reliance on TSV and CoWoS packaging is forcing equipment and materials suppliers to accelerate upgrades while reshaping EDA toolchains for 3D stacking. On compliance, U.S.-led export controls have significantly raised capex for HBM fabs, especially constraining expansion timelines for firms in Taiwan, China and mainland China, tightening supply chain security buffers. In strategic rivalry, SK Hynix leverages its HBM3E lead within NVIDIA’s ecosystem, while Samsung counters with vertical integration—shifting competition from volume to yield and delivery reliability. Over the next 12–24 months, HBM will transition from premium option to mandatory interface for AI accelerators, with its ramp pace dictating global AI infrastructure rollout and potentially triggering consolidation as laggards offload advanced packaging assets.
