Sandisk and SK Hynix release HBF spec to advance AI memory standard

The release of the HBF specification by SanDisk and SK Hynix marks a pivotal moment in AI memory architecture. This move will compel CPU and GPU vendors to optimize memory interfaces, accelerating the integration of Chiplet and high-bandwidth memory. From a supply chain perspective, the standard may trigger new technical barriers, increasing operational costs for overseas manufacturers, particularly in Taiwan and Hong Kong. Competitors like Micron and Infineon are likely to respond with accelerated patent filings to secure market positioning. In the long term, HBF will reshape the data center memory ecosystem, driving edge computing and AI inference systems toward higher performance. By 2025, it is expected to become a mainstream configuration, forcing a complete industry restructuring.
