DRAM giants target 3D stacking to break memory wall and power bottlenecks

As the semiconductor industry faces increasing demand for higher performance and greater storage capacity, DRAM giants are actively developing 3D stacking technology to overcome traditional memory wal... Read original →

The shift toward 3D stacking by DRAM leaders marks a pivotal inflection point in memory architecture. This move directly accelerates demand for advanced process nodes, particularly impacting EUV lithography and wafer suppliers. From a geopolitical standpoint, this advancement undermines U.S. dominance in high-end memory chips, offering Chinese Taiwan/ Taiwan, China and South Korean players a strategic edge in reshaping global supply chains. Market consolidation is expected to intensify, with leading firms leveraging early 3D memory investments to establish competitive moats, while mid-tier players risk obsolescence. In the long term, 3D stacking will reduce data center power consumption and enhance AI and large model training efficiency, creating new performance bottlenecks. Over the next 12–24 months, 3D stacking will become a core competitive differentiator across chip design and manufacturing, especially in HBM and memory interface standardization, triggering further industry consolidation.
