China’s YMTC Enters DRAM Market to Address Regional HBM Shortage with Domestic Production

YMTC, one of China’s leading NAND flash memory manufacturers, is venturing into the DRAM sector, with a specific emphasis on developing in-house High Bandwidth Memory (HBM) solutions. This strategic move aims to alleviate the ongoing HBM shortage that China is grappling with, largely driven by the surging demand for AI chip technology.

China’s escalating need for HBM, a crucial component for AI chips, has led to significant stock depletion, forcing the nation to rely heavily on dwindling reserves. The challenge of securing domestic HBM resources poses a greater threat to China’s tech industry than the broader issue of chip production capacity. Recently, Reuters reported that YMTC is officially entering the DRAM market to produce HBM solutions, underscoring the urgency of addressing this critical shortage.

The move by the state-backed chipmaker underscores China’s growing urgency to boost its capability to manufacture advanced chips after the U. S.expanded export controls in December to restrict Beijing’s access to high-bandwidth memory (HBM), a specialised form of DRAM used to make AI chipsets.- Reuters

In addition to focusing on HBM production, YMTC is investing in advanced chip packaging technologies, particularly Through-Silicon Via (TSV) methodologies. This technology plays a vital role in enhancing connectivity among stacked VRAM dies, which is essential for effective HBM manufacture. YMTC’s entry into DRAM production not only aims to fulfill its own HBM needs but also seeks to resolve the supply-demand imbalance that currently hampers the adoption of AI technologies among China’s leading tech companies.

Previous reports indicate that YMTC is planning to partner with CXMT, a notable Chinese DRAM manufacturer, to collaborate on the production of HBM. This partnership aims to leverage CXMT’s expertise in 3D stacking technology, which is critical for HBM development. Moreover, YMTC intends to allocate a production facility in Wuhan for its DRAM operations, although specific production timelines and output targets remain uncertain. Transitioning to the DRAM sector is a significant endeavor, and establishing a sustainable production model will take time.

Addressing the HBM supply bottleneck is a priority for many Chinese companies, particularly as competitors like Huawei unveil their own in-house HBM integration plans for next-generation AI chips. The advancement in this domain will likely have lasting impacts on the domestic tech landscape, enabling further innovation and productivity enhancements.
