具体而言，该草案将受管制物项的违规使用范围扩展至一种新情形，即外国人士通过互联网或云计算服务，在受控物项实际所在地及其境外对物项进行远 程访问。相比之下，现行美国出口管制法主要侧重于实物出口与转运的监管，以及软件销售和售后运维服务的提供。 从实际作角度看，该立法将使"远程访问"与现有的出口管制概念相当，赋予美国商务部工业与安全局（BIS）更明确的权力，要求发放许可并执行处罚， 当远程访问受控技术时。 这将与BIS现有的先进计算产品及相关活动出口管制框架并列，包括针对某些人工智能开发活动如何与出口管理局条例（EAR）管控交叉的政策指导。 众议院的这一举动是在中国企业接入中国境外领先Nvidia GPU容量的报道和政治关注之后。一个广为引用的例子是上海初创公司INF Tech与印尼的交易路 线，该交易线围绕装有Nvidia GB200系统的机架（Blackwell），估值约为1亿美元。 关于美国政策走向的更广泛背景，曾跟踪过半导体技术栈控制的持续收紧，包括影响先进制造和内存的措施。正如eeNews Europe此前报道，美国加强了 对光刻、蚀刻和HBM存储的出口管制，执法和范围一直在变化，华盛顿试图限制能力转移， ...

公众号记得加星标⭐️，第一时间看推送不会错过。 打 开 AMD 或 Nvidia 最 先 进 的 AI 产 品 包 装 ， 你 会 发 现 一 个 熟 悉 的 布 局 ： GPU 两 侧 是 高 带 宽 内 存 （HBM），这是目前最先进的内存芯片。这些内存芯片尽可能靠近它们所服务的计算芯片，以减少 AI计算中最大的瓶颈——将每秒数十亿比特的数据从内存传输到逻辑电路所需的能量和延迟。但是， 如果将HBM堆叠在GPU顶部，进一步拉近计算和内存的距离，又会怎样呢？ Imec近期利用先进的热模拟技术研究了这种情况，并在2025 年 12 月举行的 IEEE 国际电子器件会 议(IEDM) 上公布了结果，结果令人沮丧。3D堆叠会使 GPU 内部的工作温度翻倍，导致其无法正常 工作。但由 Imec 的James Myers领导的团队并没有就此放弃。他们找到了一些工程优化方案，最终 可以将温差降低到几乎为零。 一种革命性的方案 Imec 首先对一个 GPU 和四个 HBM 芯片进行了热模拟，模拟的是目前常见的封装形式，即所谓的 2.5D 封装。也就是说，GPU 和 HBM 都位于称为中介层的基板上，彼此之间的距离非常小。 ...
