HBMHigh Bandwidth Memory

AI芯片用堆叠内存

每条都摘自下方编号的来源原文;只写事实,不写预测或建议。

技术简介

  • HBM是以硅通孔互连的三维堆叠DRAM架构,相较其他内存类型提供更高带宽并降低功耗。5
    High-Bandwidth Memory (“HBM”): A 3D stacked DRAM architecture that utilizes through-silicon via connections for more efficient communication, giving it the ability to achieve a higher bandwidth while consuming less power compared to other memory types.
  • HBM不是传统平面印刷电路板设计,而是将多层DRAM裸片垂直堆叠在可选的底层裸片之上。1
    Instead of using traditional flat printed-circuit-board designs, HBM stacks multiple DRAM dies vertically atop an optional base die.
  • HBM先进封装将多层存储芯片垂直堆叠于较小面积。6
    This sophisticated process involves vertically stacking multiple layers of memory chips on a smaller footprint to reach higher computational performance and energy efficiency.

已有应用

  • 美光24GB八层HBM3E已随英伟达H200 Tensor Core GPU出货。4
    Micron’s 24GB 8-high HBM3E is shipping with NVIDIA H200 Tensor Core GPUs and production-capable 36GB 12-high HBM3E is also available.

为何此时

  • 2026年11月彭博报道,新厂拟生产的内存与英伟达加速器及全球AI数据中心需求相关,供应短缺推高价格。7
    While it isn’t considered a giant facility by modern standards, those components are intertwined with Nvidia Corp accelerators and the global AI data centre boom, and in such short supply that prices are skyrocketing.

主要参与者

  • 美光已大批量生产36GB十二层HBM4。1
    Micron is in high-volume production of HBM4 36GB 12H.
  • 三星存储业务已扩大HBM4销售,并应对服务器SSD需求增长。2
    It significantly scaled up sales of HBM4 on the back of industry-leading product competitiveness while proactively addressing growing demand for server SSDs.
  • SK海力士已开始大规模出货HBM4,其DRAM业绩也受服务器DDR5销售增长推动。3
    By product, DRAM results were driven by a significant increase in sales of server DDR5 while HBM4 shipments began in earnest.
