China's leading DRAM maker CXMT has reportedly raised its DDR5 production yield above 90%, narrowing the gap with Samsung Electronics and strengthening its position in the global PC memory supply chain.

SK Hynix is restarting a long-frozen expansion of its Dalian, China, NAND flash plant, adding capacity that will lift output at the site by roughly 50%. The move comes as the AI boom turns memory chips into one of the tightest-supplied components in the industry, according to the Seoul Economic Daily.

South Korean sensor IC designer Haechitech is moving beyond smartphone compass chips into enterprise solid-state drive temperature sensors, with supply to a major South Korean memory maker set to begin in 2026. The shift would end a single-supplier setup previously dominated by Texas Instruments and give Haechitech a foothold in the data center and memory markets.

Samsung Electronics' production yield for its sixth-generation high-bandwidth memory, HBM4, has reportedly approached 80%, marking a sharp improvement since mass production began and strengthening its ability to compete with SK Hynix on volume and cost.

SK Hynix has emerged as Kioxia's largest shareholder after Toshiba continued reducing its holding, a shift that could affect the balance of power in the global NAND flash market. The change matters beyond Japan and Korea because Kioxia's ownership is closely tied to future supply, competition, and industry restructuring worldwide.

Following growing momentum behind large-scale infrastructure buildouts in South Korea, the industry is witnessing an aggressive wave of AI-related initiatives aimed at expanding the nation's semiconductor production capacity. But the broader objective extends beyond capacity ramps alone toward building a more self-reinforcing semiconductor ecosystem across some of the most critical stages of advanced chip manufacturing.

Memory chips account for roughly 62% of the cost of Nvidia's next-generation AI platform, Vera Rubin, according to a new cost breakdown. The biggest single line item is not HBM4 but SOCAMM2, the LPDDR5X memory module attached to the Vera CPU, which runs close to US$20,000 per Superchip.

Apple's unusual interest in testing CXMT memory and redirecting part of its procurement toward China has rattled Washington, given the years-long US effort to curb China's rise across strategic segments of the semiconductor industry.

Samsung Electronics is betting on new 3D memory architectures and tighter processor-memory integration as AI workloads put growing pressure on data movement, storage capacity and power efficiency.

SK Hynix is considering options for its semiconductor packaging and testing facility in Chongqing, China, including bringing in an outside investor or selling a stake in the operation, which could be valued at about US$3 billion, as the memory chipmaker ramps up investment in South Korea.

Samsung Electronics has reportedly pushed the production yield of its sixth-generation high-bandwidth memory (HBM4) close to 80%, marking a sharp improvement from the start of mass production as competition with SK Hynix increasingly shifts toward production capacity and supply stability.

Apple has tested DRAM from China's ChangXin Memory Technologies in iPhone and MacBook products as AI-driven memory shortages and rising prices strain global supply, according to reports. The testing has also drawn bipartisan pressure from US lawmakers, who are urging the Commerce Department and Apple leadership to tighten restrictions on Chinese suppliers.

SK Hynix is facing an expanding US patent dispute with MonolithIC 3D. A second US International Trade Commission (USITC) investigation covers high-bandwidth memory (HBM) and 3D NAND products, alongside parallel litigation in federal court.
