SK Hynix says 3D DRAM will borrow from logic foundry playbook

SK Hynix's move toward 3D DRAM leveraging logic foundry processes signals a fundamental shift in memory architecture, disrupting traditional Fabless/Fab divisions. This will pressure upstream wafer fabrication to expand into storage, while downstream packaging must evolve for higher integration. From a compliance standpoint, this technological convergence may intensify geopolitical tensions, especially amid U.S.-China tech decoupling, raising supply chain security concerns. Competitors like Micron and Samsung may accelerate in-house advanced packaging R&D to maintain competitive edge. Over the next 12–24 months, integrated memory-compute designs will dominate, accelerating the blurring of logic and storage boundaries and reshaping global chip supply chains.
