Samsung advances 1d DRAM roadmap; pilot production eyed by end-2027

Samsung’s push toward 1D DRAM will force the entire memory ecosystem to requalify equipment and materials by 2027. EUV adoption, high-aspect-ratio capacitors, and novel dielectrics will raise entry barriers, disproportionately burdening second-tier players with capex. With U.S.-ROK tech alignment tightening, export controls may extend into advanced DRAM, inflating compliance costs for non-U.S. supply chains. SK hynix is likely to accelerate HBM4 ramp-up to retain premium market leverage, while Micron may pivot toward AI-optimized LPDDR5X variants to sidestep direct confrontation. Over the next 18 months, the industry enters a 'post-scaling' inflection: as process shrinks plateau, heterogeneous integration and advanced packaging—especially for Taiwan, China and mainland China players locked out of sub-1α nodes—will become the new battleground for performance leadership.
