China-based ChangXin Memory Technologies (CXMT) has moved its fifth-generation DRAM process into mass production, increasing competitive pressure on Micron in memory markets. CXMT says the platform produces at least 50% more dies per wafer than its prior process while improving power efficiency and manufacturing economics. The development could challenge Micron’s market-share and pricing assumptions, although third-party reports continue to cite tight supply and strong data-center demand.
