CHINA’S 🇨🇳 CXMT BEGINS MASS PRODUCTION OF FIFTH-GEN DRAM PLATFORM CXMT says the platform reduces key memory-cell spacing to 11.95nm using quadruple patterning, allowing more memory to be packed onto each chip. It also unveiled two new 24-gigabit LPDDR5X chips for smartphones and portable devices, each offering 50% more capacity than its previous comparable products. The manufacturing improvement is also significant: CXMT says the new platform can produce at least 50% more gross chip dies per wafer than its fourth-generation process, based on an 8-gigabit chip. That figure refers to the number of potential dies produced before defective chips are removed, not a 50% improvement in final manufacturing yield. CXMT says critical parts of the process were developed through computer simulations and joint R&D with Chinese semiconductor-equipment makers, as China continues reducing its dependence on foreign chipmaking technology.
