要了解美国对华人工智能芯片出口限制的漏洞有多大，不妨看看走私者中开始流行的一种手法，涉及一种关键类型的存储芯片。
For an illustration of how porous U.S. restrictions on the shipment of AI chips to China can be, consider a technique that has begun to catch on among smugglers involving a key type of memory chip.
尽管美国出口法规禁止向中国单独运送高带宽存储芯片，包括从韩国等国发货，但这些规定存在一个漏洞：如果这些存储芯片与性能低于出口限制门槛的廉价服务器处理器一起封装在基板上，就可以销售。根据规定，这是因为封装体的算力由服务器处理器决定，而非存储芯片。
While U.S. export regulations ban the shipment of high-bandwidth memory chips on their own to China, including from countries like South Korea, those rules have a loophole that allows the sales of those memory chips if they’re packaged together on plates with cheap server processors whose performance falls below the export restriction threshold. That’s because the computing power of the package gets determined by the server processor, not the memory chips, according to the rules.
