SK hynix took part in \u2018AI Infra Summit 2026,\u2019 held over three days on September 15th-17th (local time) in Santa Clara, California, US. The event served as a venue to examine the latest technology trends and discuss future directions across five areas: Data & Models, Compute, Data Movement, AI Data Center, and Physical AI. With global big tech companies eager to share their innovative technologies, the exhibition floor buzzed with energy.<\/p>\n
Without continued technological innovation in infrastructure fields such as servers and data centers, AI technology would struggle to sustain its current rapid growth. Underscoring the importance of AI infrastructure, this year\u2019s event drew roughly 6,000 attendees \u2014 double the figure from the previous year. SK hynix likewise doubled the size of its booth compared to last year and shared an extensive next-generation memory portfolio, reaffirming its leading technological competitiveness in AI infrastructure.<\/p>\n

\u25b2 The SK hynix exhibition booth<\/p>\n
Under the slogan \u2018New Spectrum,\u2019 the SK hynix booth focused on showcasing the company\u2019s next-generation AI memory solutions and its elevated brand presence. At the rear of the booth, SK hynix\u2019s technology vision was presented in graphic form. To its left, a dedicated space introduced technologies such as PIM and SALT-KV, while an HBF structural model was placed in front, creating a layout in which every session could be taken in at a glance upon entering the booth.<\/p>\n

\u25b2 Visitors examining the HBF structural model<\/p>\n
The HBF session consisted of an introduction video and an HBF structural model. As the AI paradigm shifts from training to inference, there is a growing need for a new memory tier between HBM*<\/span>, which offers high bandwidth, and SSDs, which can store large volumes of data. HBF (High Bandwidth Flash) is a next-generation NAND solution that applies TSV*<\/span> technology like HBM, simultaneously delivering the large capacity of conventional storage and high bandwidth. It is drawing attention as a core AI memory technology poised to open the inference-centric era of Agentic AI. Accordingly, the HBF session attracted the greatest interest from visitors at this exhibition. Many of the visitors stayed at the booth to watch the introduction video through to the end, while others spent considerable time in front of the product mock-up, closely examining the structure of HBF.<\/p>\n \u25b2 Visitors examining a server equipped with the AiMX card<\/p><\/div><\/a> \u25b2 Visitors experiencing an enhanced LLM service on a PC set up in the exhibition space<\/p><\/div><\/a> In the PIM session, SK hynix\u2019s AiM*<\/span> chip, its AiMX (AiM based Accelerator) card, and a server equipped with the AiMX card were displayed side by side, along with a hands-on demo that let visitors experience an enhanced LLM*<\/span> service firsthand. PIM (Processing-In-Memory) is a technology that embeds computational functions within memory to reduce data movement between the processor and memory. It is regarded as a next-generation solution that eases the bottleneck in data transfer (the Memory Wall) while improving both computational performance and power efficiency. Through the demo, visitors took keen interest in how much PIM technology could improve AI service efficiency, and as they viewed the server equipped with the AiMX card, they could not hide their anticipation for the fast-approaching next step in AI technology.<\/p>\n \u25b2 Visitors examining various data on the SALT-KV solution<\/p><\/div><\/a> \u25b2 Visitors building a simple game using an LLM model with the SALT-KV solution<\/p><\/div><\/a> \u25b2 Visitors building a simple game using an LLM model with the SALT-KV solution<\/p><\/div><\/a> In the SALT-KV session, a server equipped with SK hynix\u2019s eSSD was displayed, and a monitor set up beside it allowed visitors to see for themselves \u2014 through actual data \u2014 how the SALT-KV solution works and how data storage shifts within a real AI system. SALT-KV (Semantic-Aware Lifecycle Tiering for KV Cache) divides an LLM\u2019s KV cache*<\/span> into context-based segments and comprehensively assesses their reuse value and storage cost. Based on this, it places data in the most suitable storage tier among HBM, DRAM, and SSD, raising utilization efficiency within limited memory resources. Notably, this exhibition also featured a demo in which visitors used an LLM model with the SALT-KV solution to create and run a game, drawing a steady stream of visitors eager to experience the solution firsthand throughout the event.<\/p>\n \u25b2 Vice President Lim Eui-cheol (Head of Solution AT) delivering a presentation<\/p>\n Beyond the exhibition, SK hynix also conveyed confidence in its session presentation that it can fully meet the increasingly diverse needs of customers in step with the pace of AI advancement. At the Data Movement track session held on the second day of the conference, Vice President Lim Eui-cheol (Head of Solution AT) took the stage under the theme \u2018Beyond One-Size-Fits-All: PIM, HBF and More for the New Spectrum of AI Serving,\u2019 sharing the research and development achievements of next-generation technologies currently underway.<\/p>\n \u201cAs AI workloads grow more diverse \u2014 ranging from ultra-low-latency agent services to long-context services where cost efficiency is critical \u2014 the conventional GPU-HBM architecture alone is increasingly unable to meet new requirements,\u201d said Lim. \u201cIn response to these changing workloads, SK hynix is preparing new solutions that span both hardware and software: PIM, HBF, and SALT-KV.\u201d<\/p>\n He also emphasized, \u201cHBF, which combines high bandwidth and large capacity to improve the efficiency of long-context workloads, and PIM technology, which improves performance and efficiency in the fast-decoding workloads of premium services, are excellent alternatives that can move beyond existing limits. SALT-KV, too, which raises processing efficiency by taking into account the characteristics and reusability of the KV cache, holds ample potential to drive the evolution of AI systems.\u201d<\/p>\n Through its participation in AI Infra Summit 2026, SK hynix introduced next-generation AI memory solutions such as PIM, HBF, and SALT-KV, and shared its vision to lead innovation in AI infrastructure. SK hynix will continue to strengthen its technological competitiveness so that it can stay one step ahead in responding to the diverse demands of the AI era.<\/p>\n* <\/span>HBM (High Bandwidth Memory): A high-value, high-performance product that vertically connects multiple DRAM chips to increase capacity and dramatically improve data processing speed.
