AI Memory Crunch Halts Nvidia H200 Exports to China

Tight memory chip supplies are poised to limit US export licenses for Nvidia's H200 artificial intelligence processors destined for China. A new Commerce Department rule requires exporters to certify that approved shipments to China will not cause shortages within the United States market. This stipulation presents an immediate challenge due to the constrained availability of dynamic random-access memory (DRAM), a vital component for AI accelerators.

Representative John Moolenaar highlighted that chips equipped with HBM3E, bound for China, represent an opportunity cost, as this high-bandwidth memory could otherwise serve American customers. Major memory chip manufacturers, including Samsung Electronics, SK Hynix, and Micron Technology, have recently warned of limited supply. The demand for these components has surged dramatically due to the burgeoning AI data center industry.

Nvidia has stated it regularly manages its supply chain and can fulfill approved H200 orders without impacting other customers or products. The Commerce Department's new regulations, largely praised, mandate verification that China sales will not cause delays for US AI chip buyers or divert necessary foundry capacity. A hearing is scheduled for January 25th to address how memory chip availability will influence license approvals.
