Seoul [South Korea], September 22 (ANI): China’s ChangXin Memory Technologies (CXMT) commenced commercial output on its fifth-generation platform, consolidating its market position against entrenched global competitors Samsung Electronics, SK hynix, and Micron, according to a news report by The Korea Herald.

The Chinese semiconductor firm also prepares an experimental research facility in Beijing to evaluate an expansion into NAND flash memory, according to a news report by The Korea Herald.

CXMT confirmed that its G5 architecture entered volume production alongside two 24-gigabit LPDDR5X components intended for portable hardware and smartphones. Dynamic random-access memory provides real-time workspace for processors, serving as an essential building block across personal computers, enterprise servers, and mobile devices.

The chipmaker reported that the new platform delivers at least 50 per cent more gross dies per wafer compared to its previous process on an 8-gigabit-equivalent standard. Gross die count reflects the aggregate quantity of potential chips extracted from a single wafer before defect screening, rather than an outright gain in production yields.

The manufacturing rollout follows CXMT’s rise to fourth place globally in the DRAM sector, capturing 9.5 per cent of second-quarter revenue, according to TrendForce data cited in the report. Market leader Samsung held 39.4 per cent, followed by SK hynix at 24.9 per cent and Micron at 23.3 per cent.

Through quadruple patterning techniques, CXMT narrowed the active-area half-pitch in its memory array to 11.95 nanometers, a metric specific to internal array layout that does not directly match node designations used by competitors.

Assessing the competitive landscape during an industry webinar in August, TechInsights Vice President and memory-chip analyst Choi Jung-dong noted the gap between CXMT and dominant fabricators.
