Yangtze Memory Technologies has emerged in the NAND storage field, with sales share exceeding 10% globally for the first time. Its technological level is close to Samsung Electronics, with decreasing production costs. The market share is expected to continue growing, impacting the competition among Japanese, American, and Korean manufacturers.

China’s presence in the storage semiconductor sector is growing. In NAND for long-term data storage, Yangtze Memory Technologies (YMTC) has for the first time surpassed a 10% share of global sales. Currently focused on domestic Chinese business, YMTC’s growth is likely to impact operations of Japanese, American, and Korean companies like Kioxia Holdings.

“Didn’t expect the technology to improve to this level,” said a competitor’s engineer, surprised by YMTC’s new storage semiconductors set to begin mass production before February 2025. The chips feature about 270 layers, approaching Samsung Electronics’ level, using technology comparable to that of Japan, the U.S., and Korea. Additionally, YMTC has quickly adopted cost-reduction methods not yet used by other companies.

According to Hong Kong-based research firm Counterpoint, YMTC’s share of global NAND shipments reached 10% for the first time in January-March 2025. From July to September 2025, it grew by 4 percentage points to 13%, nearly matching U.S.-based Micron Technology, the world’s fourth-largest. With products mainly for Chinese laptops and smartphones, YMTC’s adoption is increasing, and its market share for the full year is expected to exceed 10%.

Japanese Economic News and the Financial Times merged in November 2015 into a single media group. The alliance, formed by two newspapers founded in the 19th century in Japan and the UK, promotes collaboration across a wide range of fields under the banner of “high-quality, most powerful economic news.” As part of this effort, articles are exchanged between the two newspapers’ Chinese-language websites.
