China's memory chip industry heads into the final quarter of 2026 riding a global supply shortage: its leading DRAM maker booked more than CNY54 billion (US$8.11 billion) in third-quarter profit, and its chip designers are still lifting sales on tight supply. The same third-quarter results also show where risks are accumulating — rapid capacity expansion, swelling inventories, and a US policy debate that could reach the equipment domestic fabs depend on.
Micron Technology and China's CXMT have taken sharply different approaches to next-generation DRAM scaling, exposing a divide over the commercial viability of 4F-squared memory-cell architecture. While CXMT is advancing 4F-squared towards commercial production to improve bit density, Micron argues that capacitor-scaling constraints undermine its cost advantages and is prioritising 6F-squared technology and a longer-term transition to 3D DRAM. Samsung Electronics and SK Hynix, meanwhile, are pursuing alternative development paths, highlighting the industry's competing approaches to extending DRAM density and manufacturing efficiency.
Nvidia will showcase its expanding partnerships with South Korean companies at AI Day Seoul, where Samsung Electronics and SK Hynix will present semiconductor development cases using Nvidia AI technologies. LG Electronics and Doosan Robotics will demonstrate robotics technologies, while SK Telecom (SKT), Naver Cloud, and Coupang will discuss the development and operation of AI data centers and infrastructure.
Apple expects record holiday-quarter revenue, but surging memory prices, supply constraints, and rising Siri AI costs threaten profitability, putting new CEO John Ternus to an early test on the company's pricing power and investment strategy. The central question is no longer whether Apple can sustain sales growth, but how much of that growth it can convert into profit.
Competition in the AI application-specific integrated circuit (ASIC) market will extend beyond 2028, industry sources said, with MediaTek, Broadcom, and Marvell competing not only for design wins, but also for secure access to wafers, advanced packaging, substrates, and high-bandwidth memory (HBM). The effectiveness of their supply-chain partnerships will determine how much revenue each company can ultimately generate.
Despite record profits driven by surging demand for artificial intelligence (AI) and a booming semiconductor industry, Samsung Electronics vice chairman and head of its Device Solutions (DS) division Young Hyun Jun said the company's technological competitiveness has yet to fully recover. He urged employees to strengthen next-generation technologies, quality, and yields, and maintain customer trust during the industry boom while building long-term competitiveness capable of adapting to market changes.
Marvell Technology's agreement to buy Lumentum Holdings would give the custom chip designer its own supply of indium phosphide (InP) lasers, one of the scarcest components in AI data center networking, and make it one of the few suppliers spanning both the electrical and optical sides of the link. The deal positions Marvell more directly against Broadcom as connections inside AI clusters move from copper toward optics packaged alongside processors and switches.
SK Hynix is increasing orders for small outline compression attached memory module 2 (SOCAMM2) printed circuit boards (PCBs) as production ramps up for Nvidia's Vera Rubin AI platform, while shortages of copper-clad laminate (CCL) and other materials are pushing up substrate prices, South Korea's Dealsite reported on October 30.
Samsung Electro-Mechanics (Semco) has begun mass production of a miniature, ultra-high-capacitance multilayer ceramic capacitor (MLCC) for advanced driver assistance systems (ADAS), as increasingly powerful automotive processors drive demand for smaller components capable of maintaining stable power supplies.
As edge AI applications and AI agents move toward real-world deployment, industrial control and embedded processors are undergoing a structural upgrade in computing capabilities.
Taiwan is aggressively pursuing a core strategy of "Team Taiwan to Team Global," according to Cheng-Wen Wu, Minister of the National Science and Technology Council (NSTC). Wu noted that when AI chips are manufactured in Taiwan, local tech companies are the first to understand their application scenarios and strengths—giving domestic industries a head start in integrating advanced AI into their own manufacturing processes.
