通信周跟踪：英伟达铜光共进趋势明朗 BIS新政或不影响国内算力建设

【中信建投：看好AI应用落地关注国产算力产业链】中信建投研报指出，近日，美国BIS正式发布了一项全球AI管控新规，涉及GPU等硬件以及将AI模型权重纳入监管范围。虽然尚不清楚接下来的特朗普政府对于这一禁令会如何处理，但美国在科技领域对于中国的封锁持续已久，国产芯片在设计、制造等关键领域也在持续突破。在美国制裁持续升级的背景下，国产算力自立自强大势所趋，建议关注GPU、交换芯片、光芯片等关键环节。

英伟达回应美国晶圆代工限制新规：不会影响公司在华业务或产品销售

【中信证券：美国对华先进存储限制再加码，倒逼高端存储产业链国产加速】中信证券研报表示，1月15日晚间，BIS修订了《出口管理条例》，修改DRAM先进存储定义，工艺节点仍为18nm，存储单元面积及存储密度由24年12月的1ynm变为1xnm，同时增加TSV通孔数限制，对HBM和先进DRAM的限制再加码，倒逼产业链国产化加速。本次限制针对制造厂商及供应链，设计厂商业务正常开展，我们看好高端定制存储业务，持续推荐。同时我们认为，后续在本土高端封测厂商和设备厂商的配合下，国内DRAM原厂有望突破HBM，布局相关环节的厂商有望核心受益，看好高端存储产业链国产替代。
