Another trillion-dollar giant is born. On the evening of May 26, Micron Technology surged, pushing its total market capitalization past $1 trillion.

Founded in 1978 in Boise, an inland small city in the United States with no existing semiconductor industry base, Micron Technology has now firmly established itself among the top three global memory chip manufacturers, sharing the DRAM market with Samsung and SK Hynix. Amid multiple industry cycles of consolidation, Japan’s memory industry has nearly faded away, and most American competitors have exited the market—yet Micron has not only survived but thrived, its journey marked by controversy and intrigue.

Throughout its development, Micron lacked policy support and substantial capital, yet repeatedly navigated industry crises through political and legal maneuvers: early on, it filed complaints against Japanese firms for dumping, acted as a leniency witness in antitrust cases to extricate itself, and subsequently spent years lobbying to influence industry competition, earning the label of a "political opportunist." Political leverage only bought it breathing room; its extreme control over manufacturing costs and decades of engineering expertise enabled smaller chip sizes and higher wafer yields, allowing it to withstand industry price cycles.

However, strategic misjudgments sowed seeds of trouble: the acquisition of Elpida caused the company to miss the golden decade of HBM, leaving it significantly behind in the high-end AI market. Today, Micron is caught in a triple squeeze—its HBM market share is vastly inferior, its mid-to-low-end market is being eroded by Chinese competitors, and its core market share in China has plummeted. While scrambling to repay its technological debt and catch up, it also faces a new round of industry competition. This chip giant, built on unique strategies and hardcore manufacturing, is under close market scrutiny as to whether it can navigate the cycle and maintain its industry position. Below, Enjoy:

Micron Technology is one of the world's top three memory chip manufacturers, alongside Samsung and SK Hynix, holding approximately 20% of the global DRAM market.

This is actually quite surprising.

In 1978, Micron Technology was founded in Boise, Idaho, USA—a landlocked small city with no existing semiconductor industry foundation. Throughout its development, it lacked government industrial policies supporting its competitors, substantial capital backing, and even a sufficiently deep technological moat.

Despite repeated cycles of collapse in the global memory industry, while former competitors from the United States gradually exited the market and Japan’s memory industry was nearly wiped out entirely, Micron Technology has managed to survive time and again.

Why is that?

The answer may lie in an unflattering detail: at the three most critical junctures, Micron’s first response was not to accelerate technological investment, but to pick up the phone and call Washington for help.

This is not to say that Micron lacks genuine technical capabilities—its manufacturing cost control has long been among the most competitive in the industry. But its ability to survive and endure ultimately stems from a survival logic that is rarely discussed head-on—and the boundaries of this logic are now being reexamined by this era.

In early 1985, Micron was the last remaining DRAM (dynamic random-access memory) company still operating in the United States.

DRAM (Dynamic Random-Access Memory) is like the "scratch paper" of electronic devices and the temporary storage space for the CPU—without it, even the most powerful CPU cannot function. At that time, Japan's six major electronics giants, backed by government industrial policies, dumped products below cost, driving out their American counterparts one by one.

Micron's situation is simple: either find another way out, or become the next one to be eliminated. But Micron's choice was to pick up the phone and call Washington.

In June 1985, Micron formally complained to the U.S. Department of Commerce about Japanese companies dumping DRAM. As the only domestic DRAM company, the U.S. could not ignore the issue and immediately pressured Japan. In 1986, the U.S.-Japan Semiconductor Agreement was signed, forcing Japanese companies to accept export price controls. According to reports, in the following years, Micron’s DRAM sales increased tenfold.

But this victory sowed an unexpected consequence: although the protocol temporarily suppressed Japan, it ceded market space to a player no one was paying attention to at the time—South Korea’s Samsung.

At the time, Samsung’s DRAM technology was just beginning and struggling to compete directly with Japanese firms, when the dispute between Micron and Japanese manufacturers presented it with a rare opportunity for growth. Ironically, Samsung’s entry into the DRAM market began with a 64K DRAM license obtained from Micron. In its early days, Micron had granted Samsung a production license to earn a substantial technology royalty fee.

In fact, when Samsung acquired this license, it was much smaller in scale than Micron and had virtually no brand recognition. However, it benefited from systemic support from the South Korean government and the chaebol system, willing to continuously invest despite losses, and endured wave after wave of industry downturns with a capital patience that Micron could not replicate.

By the mid-1990s, Samsung's DRAM production capacity had surpassed Micron's; by the 2000s, it had firmly established itself as the world's largest memory chip manufacturer, a position it holds to this day. It could be said that Micron personally "fed" the most formidable competitor it would face for decades to come.

But regardless, Micron managed to recover, at least in part, by “complaining.” However, Micron applied the same survival logic again in 2002.

That year, the U.S. Department of Justice launched an antitrust investigation into the DRAM industry, accusing multiple manufacturers of colluding to manipulate memory prices. Samsung, SK Hynix, and Germany’s Infineon were fined a combined total of over $600 million. At the time, Micron was also within the scope of the investigation.

However, Micron did not wait for the investigation to progress; even though the case had already been formally launched and Micron itself was a potential defendant, it proactively contacted the Department of Justice, submitted internal evidence to incriminate its peers, and sought immunity in exchange.

Reporting competitors to gain immunity and acting as a "leniency applicant" is standard practice under U.S. antitrust law, but in an industry heavily reliant on multilateral relationships, Micron’s move was not well received. In the end, Samsung, SK Hynix, and Infineon were fined, while Micron walked away unscathed.

In two crises, Micron escaped by using questionable political tactics, earning itself the reputation of a "political opportunist." In a fiercely competitive market with no structural advantages, Micron found a way to survive—this in itself is a form of capability.

But "all gifts bestowed by fate have already been priced in the shadows"—Micron will also pay a price for this, and that price is hidden in its 2013 acquisition.

In February 2012, Steve Appleton, the CEO who had guided Micron through a long period of ups and downs, died unexpectedly in a private aviation accident. His successor, Mark Durcan, stepped in amid crisis and immediately acknowledged an ongoing acquisition negotiation.

In July 2013, Micron completed its acquisition of Elpida Memory for approximately $2.5 billion. Elpida Memory, the last remaining legacy of Japan's memory industry, was formed by the merger of the memory divisions of Hitachi and NEC, and filed for bankruptcy in 2012 due to overwhelming debt.

On the surface, this seems like a victory. But the technological legacy left by Elpida is much weaker than imagined. Elpida’s last president, Yukio Sakamoto, stated at the bankruptcy announcement, “Elpida’s technology level is high.” This was not untrue, but that level of technology referred to a different path.

Before its bankruptcy, Elpida bet on mobile DRAM, following the smartphone market. The HBM (High Bandwidth Memory) technology path barely existed on its strategic map.

What is HBM?

If DRAM is the computer’s “scratch paper,” then HBM is its “premium 3D version.” It stacks multiple layers of DRAM chips vertically like a skyscraper, connecting them with thousands of tiny channels, achieving bandwidth ten times faster than standard memory. Regular DRAM is like a “single-story house,” while HBM is a “multi-level parking garage.” Although both use the same materials, HBM is specifically designed for AI chips (such as NVIDIA GPUs), costing 5 to 10 times more and determining the upper limit of AI computing power.

Micron didn’t just inherit Elpida’s 16,000 engineers—it also inherited an entirely different manufacturing process system. Reports indicate that the Elpida facility acquired in 2014 contributed 54% of Micron’s global DRAM production. However, more than a year after the merger, due to incompatibilities in processes, equipment, and process parameters between the Hiroshima and Boise facilities, over half of the company’s capacity continues to operate two separate process systems, resulting in significant waste.

In fact, Micron clearly listed the risk factors in its subsequent annual report, explicitly acknowledging issues such as “integration challenges with products and process technologies.”

In 2013, the same year Micron completed its acquisition, SK Hynix (formerly Hyundai Electronics) released the world's first HBM chip. This HBM vertically stacks multiple layers of memory chips, connected through tiny vias approximately 10 micrometers in diameter and 100 micrometers in depth—numbering in the thousands per layer—enabling direct connection to GPUs and increasing data throughput by several times, even up to dozens of times.

Unfortunately, in the years following the release of SK Hynix's product, there was almost no commercial market. But on the HBM track, the value of time has already been quantified into an insurmountable market barrier.

By the end of 2022, the emergence of ChatGPT instantly sparked massive demand for AI computing power, making memory bandwidth the core bottleneck of the entire system. At that time, engineers in Silicon Valley noted that about 90% of the time spent training GPT-4 was devoted to data transfer rather than actual computation—and HBM was the key to unlocking this bottleneck.

Because of this, SK Hynix, which positioned itself a decade in advance, gained a significant advantage by beginning to supply HBM3 to NVIDIA in June 2022, while Micron did not release its own HBM3 product until July 2023. Just a one-year difference was magnified into a vast gap in the rapidly evolving AI market.

At this moment, HBM3 is in high demand, with SK Hynix holding approximately 85% of the market share, while Micron, which missed the golden decade of development, holds only about 3%. This perfectly illustrates a fundamental principle of the AI era: the time that cannot be bought with money is the true value in this competition.

However, the party at a disadvantage in terms of time accumulation resorts to its habitual tactic.

In 2017, Micron’s legal team struck again. While the scale of Micron’s opponents had shrunk, the response remained exactly the same—extremely straightforward and forceful.

The first two times, the opponents were established industry giants: a price alliance formed by Japan's six major electronics conglomerates, Samsung of South Korea, and SK Hynix. This time, Micron's target is a newly established Chinese startup that has not yet achieved mass production—Fujian Jinhua Integrated Circuit (JHICC).

Micron accused Fujian Jinhua and Taiwan's United Microelectronics Corporation (UMC) of conspiring to steal its DRAM technology trade secrets. This cross-border lawsuit quickly escalated into a political action.

In October 2018, the U.S. Department of Commerce added Fujian Jinhua to its Entity List under export controls, cutting off its access to U.S. equipment and technology. A Chinese memory company that had just built a wafer fab but had not yet achieved mass production was thus stifled at the outset.

Throughout the process, Micron’s playbook in responding to competition remained exactly the same: legal action first, government intervention last, with competitors eliminated.

In the years that followed, Micron consistently pushed for Washington to tighten controls on China’s memory industry. Public records show that between 2018 and 2022, Micron spent approximately $9.54 million on political lobbying in the United States, with about 67% of those lobbying efforts related to China.

In 2022, Micron announced a $100 billion investment to build a new semiconductor fab in New York, located precisely in the district of Senate Majority Leader Chuck Schumer, one of the primary advocates of the CHIPS Act, of which Micron is also a beneficiary.

In the first two complaints, Micron won using this strategy, but by 2023, the situation had reversed.

In May of that year, China's National Internet Information Office announced the completion of its cybersecurity review of Micron products, determining that they "posed significant cybersecurity risks," and prohibited operators of critical information infrastructure from purchasing Micron products.

Micron's CFO publicly responded that the ban's impact on the company's revenue was "in the low single digits." But the reality is otherwise.

Due to Micron's early presence in China, revenue from the China region once accounted for a significant portion of its global revenue, resulting in substantial losses. According to Micron's financial report:

• Fiscal Year 2023: Due to China's countermeasures, Micron's revenue share in China decreased to 14%.

• Fiscal year 2024: Further reduced to 12.1%.

• Fiscal year 2025: This figure has dropped to 7.1%.

By the end of 2025, Micron was forced to announce its exit from the Chinese data center server chip market. Faced with China’s strong countermeasures, Micron failed to escape unscathed this time. This setback is not an isolated incident but rather a concentrated manifestation of the systemic challenges Micron has long faced.

In the semiconductor industry, high-end markets are inaccessible, while low-end markets are being eroded, and the window of opportunity in the Chinese market has already closed. These three factors coinciding in the same timeframe have created a series of unavoidable, serious challenges for Micron.

• First layer: Struggling to catch up in the high-end segment

  Micron became the second vendor to pass NVIDIA's certification for HBM3E, ahead of Samsung, finally entering the race. But this “second place” came at a cost: by the time Micron received certification, SK Hynix had already begun scaling production for the next-generation product and was continuously improving its yield, placing immense pressure on Micron. Industry analysts estimate that even at this nearly identical HBM3E stage, Micron’s market share remains under 20%, while SK Hynix’s share has long been stable above 60%.

• Second layer: Downstream market erosion

  Due to CXMT aggressively expanding its mid- and low-end DRAM production at prices roughly one-third below market rates, its shipment volume grew by approximately 50% year-over-year in 2025, rapidly increasing its market share from nearly zero to about 7%. Mid- and low-end DRAM has long been Micron’s most stable source of cash flow; as pricing margins in this segment narrow, it severely impacts the revenue Micron relies on to fund its high-end R&D. For Micron, failing to keep pace in the high-end segment means difficulty expanding its share of high-margin products, while erosion in the low-end segment means the cash flow supporting R&D is shrinking.

• Third layer: Loss of the Chinese market

  China’s ban deprived it not just of orders, but of an irreplaceable opportunity to participate. From 2023 to 2025 was the peak period for Chinese tech companies’ AI infrastructure development. This demand included massive volumes of high-bandwidth memory and premium DRAM—the very products Micron wanted to sell—but it secured not a single deal. Moreover, Chinese tech companies successfully built their AI server supply chains without Micron, while SK Hynix and Samsung secured those certification slots.

A series of setbacks have led outsiders to label Micron a political opportunist. But this can only partially explain its survival strategy—it fails to account for how it has endured through the industry’s brutal cycles. The true foundation enabling Micron to weather these storms is its unrivaled control over manufacturing costs.

Micron has indeed survived by relying on questionable political tactics and used them to suppress various competitors. But objectively speaking, Micron has only bought itself a brief reprieve and temporarily held back its rivals—it cannot fight price wars or weather industry downturns on their behalf. Competition is something it must handle itself.

Samsung and SK Hynix benefit from a chaebol structure that allows them to continue investing despite years of losses, enduring until the next market cycle turns. Micron, however, lacks this structure—it has no parent entity to provide sustained financial support, and each investment must be funded by profits earned after each price war, something that cannot be obtained merely by filing complaints.

This forced Micron to make a tough decision: continuously improve its technology to drive manufacturing costs lower than its competitors, so it could survive longer during price crashes. This capability has also been a crucial foundation for Micron’s survival and continued success to this day.

According to Micron CEO Sanjay Mehrotra:

Micron's DRAM chip has a cell area of approximately 66.26 square millimeters, smaller than Samsung's 73.58 square millimeters and SK Hynix's 75.21 square millimeters.

This means: On the same wafer, Micron can produce more chips than its competitors, resulting in inherently lower unit costs.

These advantages were not achieved through subsidies or financial backing from conglomerates, but through four decades of engineering expertise. For Micron, political maneuvering serves as a lever, providing critical time windows, but it is superior manufacturing efficiency that truly anchors its position in production. These two elements are not independent—they form an interlocking survival system, and without either, Micron would not be where it is today.

However, this combination has unavoidable limits. Political leverage and manufacturing efficiency are competitive advantages within the existing lane—they can help Micron survive, but they cannot replace the time needed to establish an early position in a new lane. Micron has survived for four decades by building cost advantages, yet on the new HBM lane, it has felt the high cost of being late.

Today, Micron has secured its certification for HBM3E, and production capacity is slowly ramping up, while the window for the next-generation HBM4 has already opened. Meanwhile, companies are continuously increasing R&D investment, deepening collaboration with NVIDIA, and leveraging the CHIPS Act to establish new product lines. All these efforts are essentially repaying the time debt incurred in the past.

After all, certification is just the entry ticket—moving from entry to stable mass production and then to profitability remains a marathon that can only be won through time and persistence. But the competition has never stopped. While Micron is working hard to fill the HBM3E capacity gap, the leaders are already optimizing the yield curve for the next-generation HBM4.

And when competition ultimately becomes a test of patience, can a company that excels at using political leverage to buy time and absorb cycles through operational efficiency win the next competition—one that demands time to prove itself?

The answer from Micron still lies within the unfinished HBM4 wafers, and in a long wait that requires true patience.
