Reportedly Evaluating 3D DRAM at Nvidia's Request
TSMC is reportedly evaluating a move into advanced memory chip manufacturing and has begun planning production of next-generation 3D DRAM. US tech outlet 《The Information》, citing people familiar with the matter on 6日, reported the plan was mainly drawn up at the request of its largest customer Nvidia. Against rapidly growing AI computing demand, memory chip supply remains tight, and tech firms including Nvidia are actively seeking additional sources of supply, prompting TSMC to begin evaluating a possible entry into the advanced memory market. If successfully advanced, it would further expand its footprint in the AI hardware supply chain.
Building a new dedicated fab or acquisition and conversion — two options
According to foreign media reports, TSMC is currently evaluating two approaches: one is to build a new fab dedicated to advanced memory chips, and the other is to acquire an existing wafer fab and retrofit its equipment and production lines for memory production. However, it remains unclear when TSMC might start production, nor which option it will ultimately adopt. The plan is said to be led by Xu Guojin, vice president in charge of advanced packaging, who previously worked at Micron, underscoring TSMC's emphasis on the integration of memory and advanced packaging.
AI Drives Demand for High-Performance Memory
As demand for high-performance memory from AI chips continues to climb, the integration of memory technology with advanced packaging has become increasingly important, and how to effectively combine memory with processors has become one of the keys to improving AI computing performance. DRAM is mainly used to temporarily store data needed for the operation of electronic devices, while 3D DRAM increases memory capacity through vertically stacking memory cells rather than the traditional single-layer horizontal layout. Successful volume production of such technology would help meet AI computing's demand for higher memory capacity and performance.
Supply-Demand Imbalance Coexists With Mass-Production Challenges
The current AI data-center buildout has left the memory market in supply-demand imbalance, with shortages pushing up chip prices and prompting large tech companies such as Nvidia and Apple to actively seek alternative sources of supply. Micron agreed in 3月 to acquire a wafer fab in Taiwan from Powerchip for 18億美元, planning to convert it into an advanced memory production base. However, the memory market is currently dominated by Samsung Electronics, SK Hynix and Micron, and has distinct cyclical characteristics. Although TSMC holds patents related to vertical DRAM technology, moving to stable large-scale mass production will still require overcoming yield and process challenges, and changes in its past collaboration with SK Hynix on base logic dies for high-bandwidth memory are also worth watching. In response to the reports, both TSMC and Nvidia have not commented.
