Samsung Electronics and SK Hynix are upgrading their NAND flash factories in China to make chips with more than 200 layers, Reuters reported on October 21, citing four people familiar with the plans. The move would let the South Korean memory makers win back ground lost to Yangtze Memory Technologies Co (YMTC), even though US curbs on upgrading their China operations remain formally in place.

With a strike by Micron Taiwan employees looming, Micron Technology said Micron Memory Taiwan and the Taichung chapter of the Taiwan Micron Memory Union had reached agreement on several issues after multiple rounds of constructive discussions. The two sides signed a labour-management agreement and agreed to withdraw the mediation scheduled for October 22. Micron will continue talks with its Taoyuan union, which has planned a one-day strike for that date.

Micron Technology said Tuesday it will fund critical minerals processing and high-purity materials manufacturing at Indium Corporation's facilities in Rome, New York.

Chinese DRAM maker CXMT is targeting higher-density manufacturing. At a recent shareholder meeting, management pledged to enter what it called the "uncharted territory" of extreme memory scaling, using process innovation to overcome technical barriers.

Axcelis Technologies plans to break ground on a US$35 million ion implantation equipment manufacturing facility in Pyeongtaek, South Korea, expanding its semiconductor infrastructure for customers worldwide. The project highlights investment in advanced semiconductor capacity as the global economy enters the artificial intelligence era, with production scheduled to begin in 2028.

Micron Technology's Taoyuan union has announced a one-day warning strike for October 22, coinciding with a second round of labour mediation between the company and its Taichung union. The Taoyuan union is demanding a concrete response to its profit-sharing proposals, particularly the percentage and amount of a one-off bonus for 2026 and a future profit-sharing framework.

Samsung Electro-Mechanics has secured a KRW360.5 billion (US$271.8 million) long-term contract to supply package substrates for memory semiconductors, strengthening its position in the growing AI server component market.

Rising memory prices are squeezing smartphone makers and consumers, pushing shipments to their lowest third-quarter level since 2012, and accelerating the market's retreat from entry-level devices. Brands are raising prices, cutting low-margin models, and limiting production, while delayed upgrades and interest in used and refurbished phones further weigh on demand.

Samsung Electro-Mechanics (SEMCO) has signed a long-term supply agreement worth KRW360.487 billion (approximately US$260 million) with a major global company for memory packaging substrates, with shipments scheduled to begin in 2027. The company did not disclose the customer or specific application, but the deal expands its long-term contract coverage from multilayer ceramic capacitors (MLCCs) and silicon capacitors into substrates.

Samsung Electronics is expected to enter 2027 with approximately 80% of its planned memory production secured under long-term contracts, reinforcing its pricing position while China's ChangXin Memory Technologies (CXMT) expands capacity and attracts attention from US tech companies seeking alternative DRAM suppliers.

Kioxia is prioritising proprietary NAND flash technology and customer-specific development over aggressive capacity expansion, seeking to capitalise on rising AI storage demand while reducing exposure to memory market volatility.

SK Hynix, South Korea's industry ministry, the state-run Korea Trade Insurance Corp. (K-SURE), and four major commercial banks launched a KRW2 trillion (US$1.5 billion) loan guarantee program for semiconductor materials, parts, and equipment (MPE) suppliers on October 19, 2026. The program is the largest single-sector package under the government's push to strengthen export supply chains, Yonhap News Agency reported.

Sandisk will be the exclusive provider of flash storage for Meta VR Glasses, supplying Meta-certified microSD Express memory cards and USB-C flash drives when the glasses launch in spring 2027, the memory maker announced in a press release issued from Milpitas, California, on October 14, 2026.

A research team at Yale University in the US has found that flowing networks made of water or other fluids can store memory like computer chips, leading to the development of a fluidic memory chip with potential applications in soft robots. The team recently published its findings in Physical Review X (PRX).

SK Hynix has presented the Memory-Centric AI Rack System (MARS) at the Open Compute Project (OCP) Global Summit. The architecture separates memory from individual servers and pools it at the rack level over Compute Express Link (CXL) fabrics. The company says this addresses the capacity and cost limits that are constraining the growth of large AI models.

The AI wave is triggering a surge in memory demand that extends from cloud data centers to edge applications. This surge has not only delivered a substantial dividend to relevant supply chains but is also driving a fundamental structural shift across the broader memory ecosystem.

The world's three largest memory manufacturers—Samsung Electronics, SK Hynix, and Micron Technology—along with Taiwan-based Nanya Technology, Winbond Electronics, and Macronix International, face significant obstacles in their transition to renewable energy.

Tesla CEO Elon Musk has predicted a surge in Chinese memory chip production by 2028, raising questions over Samsung Electronics and SK Hynix's pricing power during an AI-driven dynamic random-access memory (DRAM) shortage. His remarks suggest that China's expanding capacity could offer major technology buyers alternative sources of supply and potentially ease memory costs.

SK Hynix is strengthening its metrology and inspection (MI) capabilities as the transition toward 3D DRAM architectures and increasingly complex NAND stacking creates new challenges for conventional semiconductor inspection technologies.

AI-driven memory demand is growing exponentially, pushing the industry into a structural supply shortage. As supply tightens and contract prices surge in 2026, major AI companies and cloud service providers (CSPs) are increasingly signing long-term agreements (LTAs) lasting three to five years with memory manufacturers to secure supply and manage soaring costs.

China's leading DRAM manufacturer, ChangXin Memory Technologies (CXMT), expects to report net profit of CNY131 billion to CNY132.5 billion (≈ US$19.58 billion to US$19.8 billion) for the first nine months of 2026, reversing a year-earlier loss as surging AI computing demand fuels memory chip shortages and higher prices.

Micron is developing a memory architecture for humanoid robots, joining Samsung Electronics and SK Hynix in efforts to serve AI systems that must process sensor data while operating within battery power limits. The companies are pursuing both memory designs and storage products for robots and autonomous vehicles.

AI data center investment continues to expand, keeping the global memory market undersupplied in the fourth quarter of 2026. Rising DRAM and NAND Flash contract prices are boosting expectations for Samsung Electronics and SK Hynix in 2027, although weak consumer demand and long-term agreement (LTA) price caps will limit further increases.

This week's coverage (October 12 to October 18, 2026) highlights semiconductor capacity, AI infrastructure, and the commercialization challenges behind ambitious technology strategies. Tata's Dholera fab has early customer commitments but must convert them into qualified, recurring wafer production while facing shareholder scrutiny. Intel is rebuilding through process execution, partnerships, and advanced packaging. Micron and TSMC are expanding AI-related capacity in Taiwan and Japan, while companies including Murata, AWS, Hitachi, and XPeng advance physical AI, robotics, and engineering exports.

Nvidia's custom memory design is shifting control of how high-bandwidth memory (HBM) is built from memory makers to its largest customer, and steering a key part of that work to TSMC. Samsung Electronics, which has made every part of its HBM stacks in-house, has agreed after an internal review to use TSMC's 3nm process for the base die of NVHBM, Nvidia's next-generation custom HBM, the Seoul Economic Daily reported on October 18, citing industry sources. The newspaper said it would be the first time the two companies have worked together at the HBM manufacturing stage.
