China’s CXMT Delivers HBM3 Samples to Huawei, Potentially Resolving Major Bottleneck in Domestic AI Supply Chain

China’s leading memory chip manufacturer, CXMT, is making remarkable strides in the semiconductor industry by sending samples of its HBM3 (High Bandwidth Memory) chips to prominent domestic artificial intelligence (AI) companies, including Huawei. This initiative aims to alleviate the ongoing high-bandwidth memory crisis that has long impeded AI chip production in the country.

CXMT Plans to Launch HBM3E in China by 2027, Seizing DRAM Demand Opportunities

For several years, Beijing has grappled with an HBM supply shortfall, hindering the ability of major corporations like Huawei to enhance their AI chip manufacturing capabilities. Historically dependent on limited pre-export controlled HBM stocks, Chinese firms had struggled to develop adequate technological solutions and production capabilities. However, according to a report by DigiTimes, CXMT’s delivery of vital HBM3 samples to Huawei represents a pivotal step toward large-scale production, anticipated to commence later this year.

Analysts assert that while CXMT may lag behind the world’s top manufacturers by three to four years, its advancements mark a crucial development in bolstering China’s semiconductor independence and challenging the longstanding leadership of international DRAM producers.

Although CXMT faces technological challenges, it remains a significant player in the DRAM sector, benefiting from established production lines. The company’s DRAM output is projected to grow consistently in 2023, potentially reaching between 230, 000 and 280, 000 wafers monthly at its Chinese facilities. This capability is essential for CXMT to successfully accelerate domestic HBM technology development, especially as AI titans like Huawei and Cambricon urgently seek enhancements.

In addition to its efforts in HBM technology, CXMT is advancing in the consumer memory space, recently launching DDR5 memory modules with an impressive yield rate of upwards of 80%.Moreover, the company is expected to further boost its position through a potential initial public offering (IPO) projected for the first quarter of 2026.

The need for high-bandwidth memory was recognized as a major hurdle for China’s AI sector. CXMT’s ambition to produce cutting-edge technologies domestically underscores Beijing’s relentless pursuit of progress in AI computing. This shift is particularly significant as the country increasingly distances itself from reliance on Western technological frameworks.
