The invisible engines of our digital lives

Every time you swipe your smartphone, boot up your laptop, or stream your favorite show, you’re relying on one thing: memory chips.
These tiny, powerful devices are the silent engines that store and move the data powering our digital lives.

But behind their ubiquity lies one of the most volatile industries on the planet—a market where fortunes are made and lost in the blink of an eye.
And no company embodies that rollercoaster better than Kioxia, the Japanese semiconductor giant once known as Toshiba’s memory division.

Kioxia’s journey from massive losses to record-breaking profits is more than a comeback story—it’s a vivid illustration of the brutal, beautiful chaos that defines the global tech industry.
Here are four surprising lessons from its dramatic ride through the highs and lows of the memory market.

1. The Memory Market’s Boom-and-Bust Cycle Is Not for the Faint of Heart

The NAND flash market doesn’t move in ripples—it crashes in tsunamis.
Demand cycles are violent, prices swing wildly, and even industry giants struggle to stay afloat.

Kioxia’s financial statements read like a corporate thriller.
During one of the industry’s worst downturns, driven by oversupply and weak demand from data centers and smartphone makers, the company recorded a ¥93.3 billion operating loss in Q3 FY2022—followed by an even steeper ¥171.4 billion loss the next quarter.
Average selling prices (ASPs) plunged more than 20%, as inventories piled up and customers cut orders.

Fast forward to FY2024, and the picture flipped completely.
With the market recovering, Kioxia posted a record-high ¥166.0 billion operating profit in Q2. ASPs rebounded sharply—rising by roughly 20% in the same period.

This whiplash—from catastrophic losses to record profits—isn’t an anomaly; it’s the essence of the memory industry.
Few sectors experience such extremes, and those that survive learn to treat volatility as a core part of their DNA.

2. Global Events Hit Closer to Home Than You Think

The chips inside your devices may feel distant from global politics—but they’re deeply entangled with it.

Kioxia’s reports repeatedly underline how geopolitical tensions and global crises directly shape its business.
U.S.-China trade friction, export controls, and the war in Ukraine have all disrupted supply chains and reshaped demand. Lockdowns in China and pandemic-related logistics bottlenecks only intensified the turbulence.

COVID-19 was the ultimate case study:
Smartphone demand collapsed early in the pandemic, only for PC, data center, and gaming console demand to skyrocket months later as remote work took hold.

The takeaway is clear: the technology supply chain is now so interconnected that a policy decision or public health crisis halfway around the world can directly alter the price and availability of the chips inside your phone or laptop.

3. AI Isn’t Just About Chatbots—It’s Fueling a Memory Gold Rush

The recent revival of the memory market has one primary driver: artificial intelligence.
Training and deploying AI models demands enormous computational power and, by extension, massive amounts of high-performance memory.

Kioxia explicitly highlights this in its financial reports:

“Demand for data center and enterprise SSDs is growing due to AI demand. In addition to high demand for high-capacity SSDs for AI applications, an increase in demand for general servers is also expected.”

To seize this opportunity, Kioxia is innovating aggressively.
It has begun sample shipments of its 8th-generation BiCS FLASH™ 2Tb QLC, a cutting-edge chip enabling ultra-high-capacity storage for AI workloads.

This isn’t just about keeping up with the AI boom—it’s about building the hardware backbone for the next generation of digital infrastructure.

4. A Bold Financial Overhaul to Power the Next Chapter

Surviving in such a volatile industry requires more than great engineering—it demands financial resilience.

In July 2025, Kioxia launched a sweeping capital restructuring plan to strengthen its balance sheet and fund long-term growth.
The company took three decisive steps:

1. Raised $2.2 billion in global bonds to secure fresh capital.
2. Repurchased and canceled ¥330.4 billion of preferred stock held by the Development Bank of Japan—reducing costly obligations.
3. Refinanced ¥447.5 billion in loans with more favorable terms from a syndicate of major banks.

This wasn’t mere financial housekeeping—it was a strategic maneuver to reduce capital costs, enhance cash flow, and boost funding flexibility.
In essence, Kioxia built a financial fortress to weather future storms and invest boldly in AI-era innovation.

The Road Ahead: Building the Future of Digital Memory

Kioxia’s story offers a glimpse into the beating heart of the global tech economy—a world driven by breathtaking innovation, brutal volatility, and ever-growing interdependence.

The memory chip may be tiny, but it sits at the center of everything: from AI and cloud computing to gaming and personal devices.
As demand for data storage skyrockets in the age of AI, one question remains:

Will the next wave of technological innovation finally tame this cycle of boom and bust—or make it even wilder?

Either way, companies like Kioxia are already shaping the answer.
