CXMT is nearing LPDDR6 production. The company that just IPO'd at 470% could give Samsung and SK Hynix a competitor in next-gen phone memory.

TL;DRCXMT has nearly completed LPDDR6 R&D at 12.8Gbps. Mass production could begin H2 2026. LPDDR5X prices surged 78-83% in Q2. Samsung may skip LPDDR6 in the Galaxy S27 Ultra due to cost. CXMT could change the supply equation.

ChangXin Memory Technologies has nearly completed R&D verification for LPDDR6 smartphone memory at speeds of up to 12.8Gbps, China Business News reported. This is one of the final technical stages before trial production. CXMT could begin mass production in the second half of this year. If it does, the company that surged 470% on its Shanghai IPO debut last week would become one of the first manufacturers to ship next-generation mobile memory alongside Samsung and SK Hynix.

The timing matters because the current memory market is broken. LPDDR5X prices surged 78-83% in Q2 alone as AI data centres absorbed available production capacity, according to TrendForce. Samsung is reportedly reconsidering LPDDR6 and UFS 5.0 storage for the Galaxy S27 Ultra because of cost and mass-production concerns. LPDDR6 is expected to cost roughly 20% more than LPDDR5X, initially restricting it to expensive flagships. A second supplier with competitive pricing could change that equation.
