PHYSIX OBSERVATION

CXMT achieving simultaneous LPDDR6 mass production with Samsung and SK Hynix marks a shift for domestic storage from 'substitute' to 'price-setter.' This breaks the long-standing monopoly held by giants over the initial window of generational transitions, undermining the foundation of oligopolistic price collusion. Against the backdrop of AI computing squeezing general-purpose DRAM supply, China's rising semiconductor self-sufficiency is not just a technical breakthrough but a signal reshaping its position in the global value chain.
