SK hynix ships 12-high HBM4E samples to customers

SK hynix said Thursday it has shipped samples of high-bandwidth memory 4E (HBM4E) for next-generation artificial intelligence (AI) processors to major customers. The company said it delivered 12-high HBM4E samples on schedule, and will work closely with partners for mass production “in a timely manner.” HBM4E is the seventh generation of HBM, a high-performance DRAM designed for rapid data processing and used in graphics processing units (GPUs) and other AI accelerators that require massive computing power. The previous version, HBM4, is set to be used for Nvidia’s Vera Rubin AI supercomputer, which will be released in the third quarter, and HBM4E is expected to be used for Vera Rubin Ultra platform next year. SK hynix said the 12-high HBM4E delivers improvements in both performance and power efficiency. The product offers a maximum data transfer speed of 16 gigabits per second (Gbps) per pin and more than 20 percent higher power efficiency compared to previous models. The HBM4E reduces data transfer latency through its latest interface and design optimization while maintaining stab
