… 3 Minuten · 524 Wörter · 3,697 Zeichen 1.0× SK hynix 和 Sandisk 发布了 High Bandwidth Flash 的首批开放规范。HBF 使用 NAND 闪存，但旨在比传统 SSD 更靠近处理器运行。规划中的配置容量最高可达 512 GB，带宽最高可达 3 TB/s。这在昂贵的 HBM 与面向容量的 SSD 之间构建了一个新的存储层级。该概念主要面向 AI 推理。现代模型需要大量数据，这些数据无法全部装入 HBM，或者放入 HBM 的成本过高。如果模型权重不断从 SSD 重新加载，接口和延迟就会限制加速器。HBF 旨在直接在封装内…
… 8 Minuten · 1.437 Wörter · 11.204 Zeichen 1.0× SK hynix und Sandisk haben die ersten offenen Spezifikationen für High Bandwidth Flash vorgestellt. HBF verwendet NAND-Flash, soll aber deutlich näher am Prozessor arbeiten als eine gewöhnliche SSD. …
… Particularly when offloading large datasets or KV caches, high sequential bandwidth alone is not sufficient. …
… Kioxia positions it as an additional memory tier between High Bandwidth Memory and conventional SSDs. GPUs are expected to be able to access the flash data directly, thereby keeping larger datasets in the immediate vicinity of the computation. …
… Those who load large models locally, cache them, or continuously move data between storage, RAM, and accelerator benefit from high SSD bandwidth and low latency. …
… Faster NAND is necessary for PCIe-6.0 SSDs because the higher host bandwidth alone does not guarantee higher data rates. Controllers, Flash channels, and individual NAND packages must provide sufficient data to prevent the PCIe connection from remaining unused. …
… 2 Minuten · 268 Wörter · 1,991 Zeichen 1.0× 内存行业几十年来一直以其可靠而不可靠的周期而闻名：先是产量过剩，然后价格崩跌，随后投资被削减，最终一切又突然变得稀缺。 然而，在 SK Hynix 看来，这种熟悉的模式这一次已不足以描述当前局势。SK Hynix 首席执行官 Kwak Noh-jung 预计，2027 年将出现内存行业历史上最严重的供应短缺。在公司纳斯达克上市之际接受采访时，他于 2026 年 7 月 10 日解释说，客户需求持续上升，而生产能力在物理上仍然受限。即使在 2030 年之后，需求仍可能超过 SK Hynix 的可用产能。这一…
… While zHBM targets DRAM-based high-bandwidth memory, zNAND-O concerns the integration of NAND technology. NAND offers significantly higher capacity per unit of cost and area than DRAM, but operates with considerably higher access times. …
… For the higher transfer rates of PCIe 6.0, a wider NAND connection could once again make sense. In addition, Silicon Motion is considering larger 16 KB LDPC codewords to improve error correction with flash memory that has increasingly many cell layers. …
