While U.S. export controls shield Micron’s premium pricing for now, China’s CXMT accelerating LPDDR5X output risks triggering a price war that inflates compliance overhead. Samsung and SK Hynix will likely pivot from mature-node expansion toward silicon photonics and 3D stacking to defend margins. If Micron fails to sustain AI-DRAM yields above 85% within 18 months, its $1,100 target is untenable; success, however, could reposition the U.S. at the strategic apex of the global memory hierarchy.
