消息传播链
- 闪迪与SK海力士已在2月官宣OCP下HBF标准化工作，说明HBF主题不是首次出现。
- SK海力士确认与闪迪启动HBF全球标准化，定位为AI推理时代HBM与SSD之间的新内存层。
- 行业媒体在7月已介绍HBF路线，强调仍至少一年才可能出货且大规模部署仍偏远期。
- TrendForce披露首套HBF标准规格、Google DeepMind和Tenstorrent支持，以及375层V10 NAND路线。
- 2026-08-04 01:37 UTC其它已处理消息库非一手系统已处理同一催化：SK海力士与闪迪发布首套HBF标准规范，结论为不做且未推卡。

关键理由
- 本次事件对HBF长期生态偏正面：SK海力士与闪迪把NAND堆叠成HBM与SSD之间的新内存层，并披露最高512GB、约0.4–3.0TB/s规格。
- 不重复推卡是硬约束：已处理消息库在2026-08-04 01:37 UTC和01:52 UTC命中同一具体催化，均为不做且未推卡。
- 交易层面缺少即时业绩增量：文中商业化目标主要落在2027年、复杂内存需求约2030年起量，Hanmi等设备链也只是二阶推断且近期波动很大。
主要风险
- 若后续SK海力士、闪迪或Hanmi披露确定订单金额、量产客户或设备交付确认，需要按新事实重新研判。
- HBF仍处标准和原型阶段，NVIDIA尚未表态采用，Google与Tenstorrent支持更像生态背书而非短期订单。

[News] SK hynix, SanDisk Debut HBF Standard to Challenge AI Memory Bottlenecks with Google, Tenstorrent Support
Six months after SK hynix partnered with SanDisk to drive High Bandwidth Flash (HBF) standardization, the consortium has reached a key milestone by unveiling the first HBF standard specifications. According to SK hynix , the inaugural specification supports capacities of up to 512GB using 8-high and 16-high NAND stack configurations, with three bandwidth tiers (Grade 1–3) delivering roughly 0.4TB/s to 3.0TB/s.
The announcement came at the opening of Future of Memory and Storage (FMS) 2026, held at the Santa Clara Convention Center in California from Aug. 4–6. Notably, SK hynix also aims to accelerate adoption of an open HBF ecosystem by rallying major backers including Google DeepMind, and Tenstorrent, according to SEN TV.
The specification, disclosed through the Open Compute Project (OCP), adopts the industry-standard UCIe interconnect, enabling HBF to integrate with a broad range of processors, including GPUs and CPUs. It further defines interface and electrical characteristics, HBF die-stacking reliability and packaging guidelines, as well as software I/O requirements, SK hynix said.
As noted by Financial News , unlike HBM, which stacks DRAM dies to maximize bandwidth, HBF stacks NAND flash to deliver a new memory tier between HBM and SSDs.
According to TrendForce, HBF is emerging as a complementary technology to HBM rather than a competing one, with the potential to address HBM’s high cost and limited capacity. While NVIDIA has yet to signal adoption plans, industry sentiment remains positive, with Google and Tenstorrent’s involvement seen as reinforcing HBF’s potential to lower TCO for AI inference, TrendForce notes.
Thus, TrendForce believes the long-term architecture will likely combine HBM for ultra-high-speed computation with HBF for high-density data storage, creating a hybrid memory hierarchy that could become a key enabler of large-scale AI commercialization.
HBF Roadmap Toward Commercialization
According to SK hynix , 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.
Notably, SanDisk aims to introduce HBF prototypes in the second half of this year, with Japan emerging as a leading candidate for the production site, according to an April ETNews report. A pilot production line is expected to be completed in the second half and begin operation around year-end, with commercialization targeted for 2027, the report added.
World’s First 375-Layer V10 4D NAND Slated for Early 2027
Another key highlight was SK hynix’s unveiling of the world’s first 375-layer, 10th-generation (V10) 4D NAND, with mass production scheduled for early 2027, according to the company. The memory giant said the chip delivers a 2.5x improvement in performance per watt, targeting one of data centers’ biggest challenges: power consumption.
With 375-layer NAND-based enterprise SSDs set to enter production early next year, SK hynix said it expects to complete what it describes as the industry’s only full-stack AI memory portfolio spanning DRAM (HBM), the intermediate HBF tier, and storage (eSSD).
Another highlight of the announcement would be SK hynix’s showcase of the world’s first 375-layer, 10th-generation (V10) 4D NAND, which the company plans to begin mass production in early 2027, according to its press release.
As noted by SK hynix, the product is expected to deliver a 2.5x improvement in performance per watt to directly address one of data centers’ biggest challenges, power consumption. As its 375-layer NAND-based enterprise SSDs are scheduled to enter production early next year, SK hynix is expected to complete what it says will be the industry’s only full-stack AI memory portfolio spanning DRAM (HBM), the intermediate HBF tier, and storage (eSSD).
