-    SK hynix and Sandisk form a joint workstream under OCP to start standardization 

-    New memory layer between HBM and SSD to secure scalability and power efficiency in AI inference infrastructure

SEOUL, South Korea, Feb. 25, 2026 /PRNewswire/ -- SK hynix Inc. (or "the company", www.skhynix.com) and Sandisk Corporation held 'HBF Spec. Standardization Consortium Kick-Off' event at Sandisk Headquarters in Milpitas, California on the 25^th(local time) announcing global standardization strategy of next-generation memory solution HBF(High Bandwidth Flash) aimed at the AI inference era.

SK hynix said, "By making HBF an industry standard, together with Sandisk, we will lay the foundation for the entire AI ecosystem to grow together. A dedicated workstream under OCP^[1] will be launched with Sandisk to begin standardization work."

Recently, the AI industry is shifting from training which focuses on creating Large Language Models (LLMs) to inference, which accelerates actual AI services to users.

Fast and efficient memory is essential as the number of users using AI services increases rapidly. However, the existing memory structure cannot meet the high capacity data processing and power efficiency at the same time in the inference stage and HBF technology is designed to address these limitations.

HBF technology is a new memory layer between ultra-fast memory, HBM and high-capacity storage device, SSD. HBF technology can fill the gap between HBM's high performance and SSD's high capacity and ensure both capacity expansion and power efficiency required for AI inferencing. While HBM handles the high level bandwidth, HBF technology serves as a supporting layer in the architecture.

In particular, HBF technology is expected to reduce the total cost of ownership (TCO) while increasing the scalability of AI systems. The industry forecasts that the demand of complex memory solutions, including HBF, will pick up around 2030.

In the AI inference market, the role of a total memory solution company that can provide both HBM and HBF is becoming more important as system level optimization of CPU, GPU, and memory determines the overall competitiveness rather than the performance of a single chip.

In line with this, SK hynix and Sandisk are proactively pursuing HBF solution's standardization and commercialization based on their design, packaging and mass production experience in HBM and NAND.

"The key to AI infrastructure is to go beyond the performance competition of individual technologies and to optimize the entire ecosystem," said Ahn Hyun, President and Chief Development Officer. "Through HBF technology standardization the company will establish a cooperative system and present an AI-era optimized memory architecture to create new value for customers and partners."

SEOUL, South Korea, Jan. 28, 2026 /PRNewswire/ -- SK hynix Inc. (or "the company", www.skhynix.com) announced today that it will establish an AI solutions firm, tentatively named AI Company(AI Co.), in the US to find new AI growth engines.

"Leveraging its unparalleled chip technologies, such as HBM, the memory chipmaker will try to play a pivotal role in delivering optimized AI systems for its customers in the AI datacenter sector," the company said.

"The company will also continue making strategic investments in and collaborating with AI firms to strengthen its competitiveness in memory chips and provide a range of AI datacenter solutions."

Global big tech companies have been in a fierce competition to gain an upper hand in the AI race by making significant investments and actively seeking innovation. With the growing demand for advanced AI systems, high-end memory chips are considered essential for overcoming the performance bottlenecks of AI data solutions. Capitalizing on the AI boom, SK hynix, the world's leading memory chip maker, has been making efforts to cement its AI leadership.

In line with its AI strategy, the company is considering investing in innovative companies in the US and partnering with them through AI Co. to create synergy with the SK Group affiliates.

SK hynix will establish AI Co. through the restructuring of Solidigm (SK hynix NAND Product Solutions Corp.), its California-based enterprise SSD manufacturing subsidiary. In this process, Solidigm will maintain its entity under the name, AI Co., while transferring its business operations to a new subsidiary, to be named Solidigm Inc., to ensure brand continuity. AI Co. will serve as an AI-focused business arm, driving SK hynix's AI strategy forward. The corporate name of AI Co. will be officially announced later this year.

SK hynix will commit USD 10 billion to AI Co., with the funds to be deployed by AI Co. on a capital-call basis.

"The planned establishment of AI Co. is aimed at securing opportunities in the emerging AI era," said SK hynix, adding, "The company will continue to work closely with global partners while proactively creating value for customers."
