1. SK Hynix Develops 1c LPDDR6 DRAM, the Next-Generation Memory for AI
   SK Hynix announced today that it has completed development of 1c LPDDR6 DRAM for AI-based devices. The next-generation memory will begin shipping in the second half of 2026 and is expected to take the lead in the rapidly expanding AI infrastructure and edge device markets by meeting the demand for high-performance, low-power consumption memory. The company aims to take the lead in the rapidly expanding AI infrastructure and edge device markets by meeting the demand for high-performance, low-power memory.
2. TSMC’s February Earnings Rise Over Seasonal Slump Driven by AI Demand
   TSMC, the world’s largest semiconductor foundry, announced that its February 2026 earnings rose year over year, despite a typically seasonally slow period. This exceptional growth is largely due to exploding demand for AI semiconductors for data centers and edge devices; the expansion of AI chip production capacity is powering the company’s results and continues to play a central role in building the global AI infrastructure.
3. Samsung Labor Union Plans 18-Day Strike, Risks HBM Supply Chain
   Samsung Electronics’ labor union is planning an 18-day long strike that could have a direct impact on the company’s production facilities for high-bandwidth memory (HBM), which is seeing a surge in demand for AI servers. The risk of significant disruption to the HBM supply chain for key customers such as NVIDIA has been widely viewed by the market as a concern that could further exacerbate the global AI semiconductor supply shortage.
4. TSMC’s Arizona Plant Turns Profitable, Supporting U.S. Semiconductor Manufacturing Push
   It was reported that the Arizona plant built by TSMC in the United States has achieved a turnaround after full-scale operations. The plant has overcome challenges such as initial start-up costs and human resource shortages, indicating that a stable production system is now in place. This turnaround is an important milestone that confirms the effectiveness of the U.S. government’s policy of returning to domestic semiconductor manufacturing, and symbolizes the progress being made in the geopolitical diversification and resiliency of the semiconductor supply chain.
5. Smartphone Price Increases Begin in China; OPPO to Raise Prices by up to 500 Yuan
   Smartphone price increases are in full swing in the Chinese market. Leading manufacturer OPPO will reportedly adjust its product prices by up to 500 yuan starting March 16. The surge in semiconductor memory prices and rising costs throughout the supply chain are forcing manufacturers to pass these increases on to product prices. This is likely to be a major turning point for improving the profit structure in the Chinese smartphone market, where intense price competition has continued until now.
6. Nexperia’s Chinese Subs idiary Rebels Against Dutch Headquarters, Starts 12-inch Factory
   The Chinese subsidiary of Nexperia, a semiconductor company based in the Netherlands, has reportedly started manufacturing new 12-inch chips against the wishes of its headquarters. This is a move by a domestic Chinese base to expand its own production capacity and force the supply chain to become completely homegrown and self-reliant in the face of increasing restrictions on semiconductors in China by the U.S. and Europe. This is a shocking situation that highlights the geopolitical divide between nations within global companies and the governance risks unique to the Chinese market.
7. ROHM Acquires GaN Technology License from TSMC, Will Build Production Line by 2027
   ROHM, a Japanese semiconductor manufacturer, has acquired a license for GaN technology, a next-generation power semiconductor material, from TSMC, the world’s largest foundry. Based on this partnership, ROHM plans to build a new production line for GaN products by 2027. The strategy is to strengthen its own manufacturing base and dramatically increase its global competitiveness in the power semiconductor market, where demand is growing for AI servers and electric vehicles, which require highly efficient power conversion.
8. Applied and Micron Partner to Accelerate Development of HBM and Next-Generation Memory
   Applied Materials, the largest supplier of semiconductor manufacturing equipment, and memory giant Micron have entered into a strategic partnership to accelerate the development of next-generation memories such as HBM, NAND and DRAM.AI As demand for high-performance memory for infrastructure explodes, the partnership aims to dramatically increase the speed of mass production by overcoming the technical hurdles in manufacturing associated with miniaturization and layering through close collaboration between equipment manufacturers and device manufacturers.
9. Amazon Raises Over 6.3 Trillion Yen in Corporate Bonds, Accelerating Massive Investment in AI Infrastructure
   Amazon plans to raise a massive amount of over 6.3 trillion yen through the issuance of corporate bonds, it has been revealed. The huge amount of funds raised is expected to be used intensively for investment in AI infrastructure, including expansion of data centers to support the rapidly expanding generated AI services and development of proprietary AI semiconductors. As the battle for AI supremacy among giant IT companies intensifies, the race to build overwhelming infrastructure backed by astronomical financial resources is becoming even more heated.
10. NVIDIA Invests in Former OpenAI Executive’s Startup to Support Semiconductor Ecosystem
    NVIDIA, the market leader in AI chips, has invested in a new AI startup founded by a former OpenAI executive. NVIDIA is not only supplying hardware, but also making strategic seed investments in promising AI startups to build and expand a robust AI ecosystem based on its semiconductors. This is a move that will further solidify NVIDIA’s dominance in the AI industry from both a software and hardware perspective.
