SK Hynix invests $64 billion in AI memory chips as NAND flash shortage intensifies

SK Hynix Investment Targets Memory Chip Manufacturing Expansion

SK Hynix plans to invest 100 trillion won, approximately $64 billion, to construct new facilities for AI memory chips and NAND flash memory production in Cheongju, South Korea1

. CEO Kwak Noh-jung announced the plan at an event attended by President Lee Jae Myung, breaking down the spending into two major projects. The company will allocate 80 trillion won, or roughly $51.46 billion, to build a new NAND factory called M17, with production targeted to begin in the first half of 20291

. An additional 20 trillion won will fund a chip packaging plant known as P&T7, scheduled for completion by late 20272

This SK Hynix investment forms part of a broader $2.1 trillion plan unveiled alongside Samsung Electronics, aimed at doubling South Korea semiconductor production capacity within five years3

. Construction on the M17 factory is expected to begin next year, giving the company roughly three years to bring the facility from groundbreaking to output1

AI-Driven Memory Demand Creates Supply Constraints

The massive capacity buildout addresses a global shortage of memory chips driven by AI datacentre buildouts and hyperscalers demanding more storage alongside compute power1

1

. Industry trackers including TrendForce and DigiTimes have flagged tightening NAND supply as operators buy up storage, even as most attention around SK Hynix's stock rally has centered on HBM memory1

1

. At the Thursday event, Kwak expressed confidence in the market, stating that "while demand for NAND has been increasing and is expected to continue growing in the future, NAND supply is constrained"5

.

NAND flash memory, which retains data even when devices are turned off, handles long-term data storage in solid-state drives, distinct from DRAM and HBM used as working memory inside AI servers1

1

. Reuters and Nikkei Asia have linked the spending spree to warnings that the global memory shortage could persist into 2027 rather than easing this year1

1

. The shortage has already rippled into consumer electronics, with memory prices climbing sharply enough that Apple discontinued its entry-level Mac Mini1

Advanced Packaging and Strategic Positioning

The P&T7 facility in Cheongju will focus on wafer-level packaging and advanced packaging for AI memory, including high-bandwidth memory4

4

. This represents a critical component of the company's strategy, as NAND capacity additions and HBM supply increasingly compete for the same wafer starts and packaging capacity inside SK Hynix's Korean plants1

1

. The M17 factory will be SK Hynix's fourth NAND fab and represents a bet that flash storage still needs serious new capacity despite being the less glamorous half of memory chip manufacturing compared to HBM chips that feed AI accelerators1

1

.

Cheongju, already home to SK Hynix's existing NAND operations, is becoming the center of gravity for the company's storage ambitions well into the next decade1

1

. SK Hynix overtook Samsung Electronics last year as South Korea's most valuable listed company, driven almost entirely by the HBM boom, making this fresh bet on NAND flash memory notable1

Market Concerns and AI Infrastructure Spending Questions

Despite the confident outlook from executives, semiconductor shares faced significant pressure following the announcement. SK Hynix shares slumped 7.1% and Samsung shares dropped 8.6% on Thursday, hit by a global selloff in chipmakers as Meta Platforms' plan to sell computing power raised questions over excess AI computing capacity2

. The massive capacity buildout is a major political win for President Lee Jae Myung, though it is stoking fears of a painful reckoning if AI infrastructure spending cools4

4

.

Investor Michael Burry, known for his successful bets against the U.S. housing market in 2008, expressed caution about the massive South Korean investment plan, with the Wall Street Journal reporting he sees it as "the beginning of the end" and has made bearish bets against AI-related stocks4

4

. SK Hynix cautioned in a filing that long-term investment plans could change depending on global chip demand and spending by major customers, with factors such as delays in selecting and securing construction sites potentially causing postponements4

4

. The scale of response from SK Hynix and Samsung Electronics suggests both expect the squeeze to last well beyond the next product cycle, treating memory chip manufacturing dominance as a national strategic asset worth defending1
