三星电子同时宣布计划回购3.57万亿韩元（约合25亿美元）的股份，以回馈股东。继公司股价在2025年实现翻倍之后，本月又上涨约 35%，反映市场对其AI相关业务的高度预期和投资信心。 AI推动半导体芯片部门业绩大增 三星半导体部门贡献了其中的16.4万亿韩元（约合114亿美元）营业利润，贡献了集团80%的营业利润，远超分析师平均预期的10.85万亿 韩元（约合75.6亿美元）。该部门运营利润的强劲增长主要得益于AI高性能计算服务器及数据中心对高带宽存储（HBM）产品的旺盛需 求。 高带宽存储（HBM）相比标准DRAM，每单位内存所需晶圆产能约为三倍。这导致部分传统DRAM和NAND供应紧张，推动个人电脑和 智能手机用存储芯片价格上升。这一供需紧张直接为三星电子和竞争对手SK海力士创造了显著收益。 SK海力士在1月28日公布的财报显示，该公司同样录得历史新高营收与利润。其HBM产品在AI市场需求推动下表现出强劲增长，成为公 司盈利的重要支撑。Pictet资产管理高级投资经理李英宰（Young Jae Lee）表示："SK海力士在HBM技术上仍领先，而三星电子正全力追 赶。投资者将密切关注两家公司对存储市场前景的 ...

Core Insights - The semiconductor industry's profit structure is changing due to the rapid increase in demand for artificial intelligence (AI) and a significant rise in memory prices [2] - Samsung Electronics and SK Hynix are expected to surpass TSMC in gross margin by Q4 2025, marking the first time since Q4 2018 that the memory industry outperforms foundries [2] - Micron, the third-largest memory manufacturer, anticipates its gross margin to reach 67% in Q2 of FY2026, indicating potential for profitability to exceed TSMC as well [2] Group 1: Memory Market Dynamics - The three major memory manufacturers have allocated approximately 18% to 28% of their DRAM capacity to high bandwidth memory (HBM), which has led to a quarterly price increase of over 30% for standard DRAM [2] - The shift in memory gross margins surpassing foundries is closely linked to changes in AI industry demand structures [2] Group 2: AI and Memory Technology - As AI applications transition from training to inference, the demand for high-speed data storage and instant access has significantly increased, relying heavily on HBM to supply data to GPUs for computation [3] - Despite general memory not matching HBM's performance, the demand for high-performance general memory is rapidly growing, with GDDR7 and LPDDR5X handling initial inference workloads [3] - Memory manufacturers are developing AI-oriented high-performance products, such as Processing-In-Memory (PIM) technology, which allows memory to perform some computations traditionally handled by GPUs [3]

一份SK海力士内部分析文件意外曝光，揭示了全球存储芯片市场面临的严峻供需失衡。该文件显示，除HBM和SOCAMM外， 标准DRAM的供应紧张将持续到2028年，这一预测比瑞银此前预计的2027年一季度更为严峻。 据社交平台X用户@BullsLab上周分享的截图，SK海力士认为标准DRAM的产能增长将受到严重制约。供应商库存正被消耗至最 低水平，而生产产能相比以往上升周期预计增长有限。 这一供需格局将对全球科技产业链产生深远影响。据华尔街见闻此前文章，瑞银预测今年四季度DDR合约价将环比上涨35%， 2026年一季度将进一步上涨30%。苹果等科技巨头也将面临成本压力，其与三星、SK海力士的长期供应协议将于2026年1月到 期。 人工智能需求激增成为推动这轮"超级周期"的核心动力。SK海力士预计，AI服务器市场份额将从2025年的38%飙升至2030年的 53%，带动DRAM需求实现24%的强劲增长。 即便利用现有厂房进行技术转换也面临挑战。无论是DDR4停产转向DDR5，还是NAND制程转换为DRAM生产，都需要相当长 的调整周期。这使得短期内通过产能调配缓解供需矛盾变得困难。 与此同时，供应商库存水平正急剧下 ...
