Micron Technology MU, the memory and storage chipmaker, faced a fresh challenge in mobile memory after China’s CXMT announced mass production of its fifth-generation DRAM platform. Micron shares fell about 1.4% to $1,080.47 Wednesday morning.
CXMT says two new LPDDR5X chips each hold 24 gigabits, 50% more than its previous comparable products. It also claims the new process produces at least 50% more gross dies per wafer than its prior platform, using an 8-gigabit baseline. More potential output could make CXMT a tougher competitor on cost. But gross dies are a production measure; they do not tell investors how many usable chips leave the factory.
That distinction matters for Micron. CXMT’s announcement points to more competition in mobile DRAM, but it does not show the customer volumes or yields needed to measure the threat. It also does not establish a rival to Micron’s high-bandwidth memory for AI systems; Micron said it began volume shipments of HBM4 earlier this year. Meanwhile, the picture puts Micron’s share price 67.17% above its $646.32 GF Value. That gap leaves investors watching both sides of the story: how well Micron sells premium AI memory, and whether new conventional DRAM supply weighs on pricing.
