SK hynix Moves HBM4E Forward With 12-High Sample Shipments

SK hynix has announced sample shipments of its 12-high HBM4E product to major customers as it prepares for eventual mass production. According to the company, the memory reaches up to 16Gbps per pin, offers more than 20% better power efficiency than the prior generation, and delivers 48GB per package. The product also uses the company’s MR-MUF packaging approach and is described as offering better heat resistance and lower latency for demanding AI workloads. For the memory market, the announcement reinforces SK hynix's push to stay at the front of the HBM roadmap as AI infrastructure scales. While this is not the same as volume shipment, successful qualification could strengthen future supply positioning in premium AI memory segments.
