On October 30, ChangXin Memory Technologies (CXMT), a leading domestic memory chip company, announced at its Q3 earnings briefing that its 6th-generation process technology platform has completed engineering sample validation, following a key breakthrough in the 4F² vertical channel DRAM architecture. Completion of engineering sample validation indicates that the platform's core performance metrics have met design expectations on actual wafers, and that it can advance to the mass production stage once client-side validation is completed.
