SK hynix has solidified its leading position in the AI memory sector by delivering initial samples of its cutting-edge 12-layer HBM4E to key clients. This advanced high-bandwidth memory (HBM) solution achieves a remarkable data transfer rate of up to 16 Gbps per pin and significantly enhances power efficiency by over 20% compared to its predecessors. Furthermore, its optimized interface and design contribute to a notable reduction in data transfer latency, marking a substantial leap forward in memory performance.

A critical innovation in the new HBM4E is its utilization of Advanced MR-MUF technology, enabling a 48GB capacity within a 12-layer stack. This design also yields a 17% reduction in heat resistance compared to HBM4, a crucial factor for maintaining stability and efficiency within the demanding environments of modern AI data centers. These enhancements reinforce SK hynix's status as a top-tier HBM provider, positioning the company strategically at the forefront of the evolving AI accelerator memory landscape.

This latest development further underscores the company's strong performance, following a robust first quarter in 2026 where revenue surged by 198.1% year-over-year to 52.57 trillion won. This growth was primarily fueled by robust demand from the artificial intelligence sector and increased sales of high-value memory products. SK hynix's consistent innovation and market responsiveness make it a clear beneficiary of the ongoing high-bandwidth memory upgrade cycle, driving technological progress and supporting the rapid expansion of AI applications across various industries.
