Recently, Micron Technology announced that a groundbreaking ceremony was officially held for its advanced memory chip factory in Hiroshima, Japan, with a total investment of approximately 1.5 trillion yen (about $9.3 billion). The factory will focus on producing key AI chips such as HBM (High Bandwidth Memory), with mass shipments expected around 2028.
At the same time, new factories in multiple regions including the United States, Japan, Singapore, and Taiwan (China) are also progressing simultaneously, covering core products such as DRAM, HBM, and NAND Flash.
This is not an ordinary capacity expansion, but a competition for the right to speak regarding AI infrastructure over the next decade. In the coming years, whoever possesses more advanced memory capacity may hold the most central voice in the AI industry chain.
I. From Consumer Electronics to AI Computing Power: The Memory Market Ushers in Structural Change
Over the past few decades, the storage industry has been one of the most cyclically volatile areas of semiconductors. DRAM and NAND products are highly standardized, and the industry has long followed the classic cycle of rising demand, capacity expansion, oversupply, price collapse, and production cuts.
Therefore, Micron rarely engaged in such aggressive large-scale capital expenditure in the past, preferring to adjust capacity based on market conditions. However, the emergence of AI has completely changed this logic.
In the past, whether for personal computers or smartphones, the demand for memory capacity grew relatively slowly; adding a few GB of memory to a device was sufficient to meet upgrade needs. However, the data processing methods of the large model era are completely different.
New-generation AI, represented by large language models such as GPT, Gemini, and Claude, requires tens of thousands or even hundreds of thousands of GPUs for collaborative training, and each GPU requires a large amount of HBM as a high-speed cache. Without sufficient HBM, no matter how powerful the GPU's computing capability, its performance cannot be fully utilized.
It is precisely for this reason that HBM has gradually become one of the most scarce components in the entire AI server ecosystem.
Industry data shows that the value of HBM required for a high-end AI GPU has approached or even exceeded the price of a traditional server CPU. As GPUs continue to upgrade, the HBM capacity required for each generation of products also continues to increase, driving the HBM market into a phase of rapid growth.
Furthermore, AI has also driven a simultaneous increase in demand for traditional DRAM and NAND.
New applications such as AI PCs, AI phones, autonomous driving, edge AI servers, and intelligent robots are constantly emerging, pushing the entire storage market into a cycle of structural upgrades. Micron expects that the supply-demand tension driven by AI will last at least until after 2026, and truly large-scale new capacity will not be released until around 2027 to 2028.
This means that in the next two to three years, the global high-end storage market will still be in a state of supply shortage. For this reason, Micron has chosen to lay out its plans in advance, hoping to capture more market share in the next industry cycle, rather than hastily expanding capacity after demand explodes.
From a business logic perspective, this is more like building the highways for the AI era in advance, rather than simply adding a few production lines.
II. Reshaping the Global Manufacturing Landscape: Micron Builds an AI-Era Supply Chain
If you look closely at this capacity expansion layout, a distinct characteristic becomes apparent. Micron has essentially re-planned almost all of its major global manufacturing bases, with the United States being the core of this expansion.
At its Manassas, Virginia facility, Micron has already achieved mass production of the 1α (1-alpha) nanometer process and, through a $2 billion expansion project, has quadrupled its DDR4 wafer supply capacity, focusing on the automotive electronics, industrial control, and defense markets.
More importantly, the company is re-establishing advanced DRAM manufacturing capabilities within the United States.
The new factory in Boise, Idaho, involves an investment scale of $50 billion, making it one of the largest semiconductor manufacturing projects in the U.S. in recent years. At the same time, Micron announced it would expand its overall U.S. investment to approximately $200 billion, including advanced manufacturing and R&D system construction, and add a second wafer fab.
Furthermore, the Clay mega-fab project in New York State is on a scale exceeding $100 billion. It will involve the construction of multiple wafer fabs in the future, with the goal of forming one of the world's largest DRAM manufacturing bases around 2030.
Behind these investments, a key keyword is supply chain localization.
In recent years, the United States has been continuously promoting the reshoring of chip manufacturing to reduce dependence on the Asian supply chain. The introduction of the CHIPS and Science Act has provided substantial financial subsidies and tax incentives for companies including Micron, also reducing the cost pressure for companies building factories in the U.S.
At the same time, Micron has not abandoned Asia.
The Hiroshima factory in Japan, which will focus on producing HBM in the future, is considered one of the most strategically valuable projects in this expansion. Japan possesses a mature semiconductor materials, equipment, and packaging industry chain, coupled with government subsidy support, making it once again an important base for advanced memory manufacturing.
Singapore, on the other hand, will undertake advanced NAND manufacturing tasks. It has a well-established electronics manufacturing ecosystem, a stable policy environment, and international logistics advantages, making it suitable as a global supply center.
Acquiring the Powerchip Semiconductor Manufacturing Corporation (PSMC) fab in Tongluo, Taiwan (China), will help Micron quickly expand its DRAM manufacturing capacity and shorten the construction cycle for new factories.
It can be seen that Micron's global layout is not simply about maximizing capacity, but about deploying different products in different regions to achieve risk diversification, supply chain security, and cost optimization.
This type of layout is increasingly becoming the new normal for global semiconductor companies.
III. In the AI Era, Can Micron Become the Biggest Winner in the Storage Industry?
The most concerning question for the capital market is actually just one: can such a massive investment be recouped in the future? The answer largely depends on whether AI demand can be sustained. Currently, the outlook leans towards optimism.
Global cloud computing vendors are continuing to expand their AI capital expenditure. Tech giants like Microsoft, Google, Meta, and Amazon are investing tens of billions of dollars annually in building AI data centers.
At the same time, an increasing number of traditional enterprises are also beginning to deploy AI computing infrastructure.
As new applications such as AI Agents, multimodal models, video generation, autonomous driving, and humanoid robots continue to be implemented, the demand for high-performance storage is still growing rapidly.
Compared to the GPU market, which is mainly dominated by a few manufacturers, the HBM market is still in a phase of rapid expansion.
In the past, the high-end HBM market was long dominated by SK Hynix, with Samsung Electronics following closely, while Micron entered relatively late. However, in recent years, Micron has successfully entered the mainstream AI supply chain with products like HBM3E and obtained certifications from key customers, and its market share is rapidly increasing.
In the coming years, HBM may become one of Micron's fastest-growing profit businesses.
Of course, risks still exist.
The biggest characteristic of the semiconductor industry is cyclical fluctuations. If the pace of AI investment slows down in the future, or if new global capacity is released intensively, DRAM and NAND prices could still re-enter a downward cycle.
Furthermore, Samsung Electronics and SK Hynix are also continuously expanding capacity, making future market competition even fiercer. Advanced process technology, packaging capabilities, yield control, and customer certification will all determine who can truly win orders in the AI era.
However, unlike the past reliance on consumer electronics, AI demand is now changing the business model of the entire storage industry.
More and more high-end storage products are adopting long-term supply agreements, forming more stable cooperative relationships with cloud computing vendors and AI chip companies. This means that future industry price fluctuations may be somewhat moderated compared to the past, and corporate profitability may also become more stable.
For Micron, this round of capacity expansion is not just about increasing capacity, but also about redefining its role in the global semiconductor industry — transforming from a traditional memory chip manufacturer into a key supplier of AI infrastructure.
Conclusion
GPUs determine the computing power of AI models, while HBM, DRAM, and NAND determine whether data can be quickly stored, accessed, and transferred. Without high-performance storage, even the most powerful AI models would struggle to reach their full potential.
Therefore, Micron's global expansion spanning the United States, Japan, Singapore, and Taiwan is not merely a manufacturing investment plan, but a strategic layout for AI infrastructure over the next decade.
It is foreseeable that in the coming years, the global storage industry will usher in a new wave of capital investment, technological upgrades, and market competition. Micron's global expansion plan, launched this time, may only be the beginning of this AI storage war.
