China's CXMT expansion threatens global memory market dominance

China's largest DRAM manufacturer, CXMT, is rapidly increasing its memory production capacity, posing a potential challenge to the established global hierarchy of memory giants. The company, already profitable in the general DRAM market for PCs and smartphones, is accelerating its development of high-bandwidth memory (HBM), signaling an intensified competition in the high-value memory sector.

According to SemiAnalysis, CXMT's production capacity is projected to reach 350,000 wafers per month by the end of this year, narrowing the gap with Micron Technology, the third-largest memory company, which produces 385,000 wafers monthly. CXMT is pursuing an initial public offering on the Shanghai Stock Exchange to raise approximately 29.5 billion yuan. These funds are intended to fuel research into next-generation DRAM and expand production lines to enhance competitiveness.

Industry observers anticipate that following its IPO, CXMT's monthly output will climb from 350,000 wafers this year to 420,000 next year, and reach 500,000 by 2028 – an increase of over 42% in two years. This aggressive expansion strategy is driven by the surging demand for DRAM memory, fueled by increased investment in AI servers.

While the top three memory makers, Samsung Electronics, SK Hynix, and Micron, are focusing on high-value products like HBM for AI servers, CXMT aims to significantly boost its HBM production post-IPO. This push is backed by strong Chinese government support for the high-value semiconductor sector, with the goal of achieving technological self-sufficiency. CXMT is actively developing its fourth-generation HBM3 and fifth-generation HBM3E, with plans to mass-produce HBM3E products next year to meet global AI chip company demands. SemiAnalysis forecasts CXMT's HBM production to grow by over 80% from 55,000 wafers per month next year to 100,000 by 2028.

Kim Hyung-jun, a professor at Seoul National University and head of the Next-Generation Smart Semiconductor Program, noted that while China still trails Samsung and SK Hynix by two to three years technologically, their rapid acceleration in production and R&D after IPOs is a cause for concern.

From a technical perspective, there is still a 2-3 year gap between China and companies like Samsung Electronics and SK Hynix. However, what is concerning is that these Chinese companies are accelerating their catch-up through capacity expansion and R&D after their IPOs.
