YMTC's Phase 3 Wuhan fab is set to open later this year, meeting Beijing's requirement for new Chinese fabs to source at least 50% of their equipment domestically. The company plans to add two more fabs of similar scale in the future. The move towards 3D NAND production leverages China's strengths in wafer bonding technologies. Despite reliance on imported lithography tools, YMTC aims to achieve 50% domestic tooling by substituting in other areas like etch, deposition, and cleaning. Additionally, part of the new fabs' capacity will be allocated to DRAM production, with YMTC making strides in developing its own DRAM technology.

China's premiere memory-maker YMTC plans two additional Wuhan fabs using homegrown chipmaking tools — Phase 3 crosses 50% domestic tooling threshold

China's Yangtze Memory Technologies (YMTC) is expanding its memory production with plans for two new fabs in Wuhan, in addition to the Phase 3 plant set to be completed this year. Each new plant will have the capacity to produce 100,000 wafers per month, doubling YMTC's current output. With over 50% of Phase 3's equipment sourced domestically, YMTC is testing the viability of Chinese chipmaking tools for high-volume 3D NAND production. The company aims to increase DRAM and NAND production, with a focus on developing through-silicon via packaging for high-bandwidth memory. Despite challenges, YMTC holds a significant share of the global NAND market and is projected to grow further by 2028.

Kioxia discontinues 2D NAND products, last shipments to be made in 2028 — 1980s planar NAND memory reaches end of life

Kioxia discontinues 2D NAND products, last shipments to be made in 2028 — 1980s planar NAND memory reaches end of life

Kioxia is discontinuing production of its 2D NAND and 3rd Generation BiCS 3D NAND memory, with last shipments scheduled for 2028. This move marks the end of planar NAND memory, a technology that has been in production since the 1980s. The phase-out includes various legacy NAND products built on different nodes and cell types, covering a wide range of delivery formats. As Kioxia shifts focus to more advanced 3D NAND nodes, the decision to discontinue 2D NAND aligns with the changing demands in the industry, particularly from the AI sector.

China's premier memory-maker YMTC struggles amid chokehold of US sanctions — outdated chipmaking tools and lack of new tools have hampered production and development of new tech

China's premier memory-maker YMTC struggles amid chokehold of US sanctions — outdated chipmaking tools and lack of new tools have hampered production and development of new tech

China's memory-maker YMTC is struggling to expand production capacity due to U.S. export restrictions on advanced chipmaking tools, causing its market share to drop below 5% in Q2 2025. Despite developing cutting-edge technologies like Xtacking 4 and hybrid bonding, YMTC can't grow its fabs due to sanctions. The company's progress faltered after U.S. export restrictions on wafer fab equipment, hindering its ability to increase manufacturing capacity. While YMTC continues R&D on 5th and 6th Generation 3D NAND devices, the lack of new tools and outdated equipment are limiting its options and impacting competitiveness against industry rivals.
