ChangXin Memory Technologies has announced that its fifth-generation dynamic random-access memory platform, designated as the G5 platform, has officially entered volume production. The Hefei-based manufacturer stated that the new process platform reduces the active-area half-pitch of its memory array to 11.95 nanometers and achieves a 45-to-1 capacitor aspect ratio, significantly increasing memory density and wafer output compared to previous iterations. The announcement follows ongoing geopolitical tensions and strict United States export controls designed to limit China's semiconductor capabilities. Despite being placed on a Pentagon blacklist and facing scrutiny from American lawmakers regarding supply chain integration, CXMT continues to expand domestic fabrication lines. The newly mass-produced G5 platform includes 24-gigabit LPDDR5X products targeted at mainstream domestic flagship smartphones. Industry analysts note that the commercial scaling of these components highlights the resilience of China's domestic semiconductor sector amid broader global supply chain shifts and ongoing technological competition across the modern global market.
