CXMT cashes in on the DRAM shortage — and takes aim at HBM

By capitalizing on the DRAM shortage, CSUN has achieved a turnaround in profitability, signaling a shift in China's memory industry from follower to leader. Technologically, this boost in margins enables further R&D investment in LPDDR6 and HBM, exerting upward pressure on upstream materials like silicon wafers and photoresists. From a compliance standpoint, while domestic substitution accelerates, geopolitical tensions persist, especially in accessing critical equipment and technologies. Competitors such as Micron and Samsung may respond with increased capacity expansion, but CSUN’s cost advantages and policy backing position it to break into high-end memory segments. Over the next 12–24 months, China’s memory sector will deepen upstream integration, forming a more self-sufficient ecosystem and reshaping global DRAM pricing dynamics.
