SK hynix Ships Samples of 12-Layer Next-Gen 'HBM4E' - PR Newswire

SK hynix has shipped samples of its next-generation 12-layer HBM4E high-bandwidth memory to major customers, marking a significant advancement in memory technology for AI workloads. The new product de... Read original →

SK hynix’s early shipment of 12-layer HBM4E isn’t just a product milestone—it forces a cascade of redesigns across the HPC stack. EDA tools and TSV equipment vendors must rapidly align with MR-MUF integration, while GPU makers scramble to re-engineer interconnects for 16Gbps/pin throughput. Tightening U.S. export controls on advanced packaging raise compliance costs for non-U.S. clients, compelling SK hynix to dual-source production between Korea and its Wuxi facility in China. With Samsung racing to ramp HBM4 and Micron deepening CoWoS ties with NVIDIA, SK hynix is betting its full-stack memory expertise will lock in AI infrastructure dominance. Within 18 months, HBM4E will shift from premium option to system necessity, making 3D-stacked DRAM inseparable from next-gen AI training clusters—and triggering a parallel revolution in thermal and power delivery architectures.
