On September 20, during the 2026 World Manufacturing Convention, Changxin Technology made a significant announcement: the official commencement of mass production for its cutting-edge fifth-generation technology platform. This platform boasts a half-pitch of a mere 11.95 nanometers within the memory array's active region, coupled with a remarkable memory capacitor depth-to-width ratio of 45:1. Additionally, it has achieved a notable reduction in the height of the core kinetic area to 6762 nanometers, leading to a substantial boost in storage density. In comparison to its predecessor, this platform has witnessed an impressive surge of over 50% in wafer output per unit under identical conditions. The 24GB LPDDR5X product, built upon this advanced platform, has officially entered the mass production phase and is now seamlessly integrated into mainstream flagship smartphones manufactured domestically.
