〔編譯魏國金/台北報導〕韓國KB證券11日預測,由於高頻寬記憶體(HBM)市占率提高,以及晶圓代工良率改善,三星電子未來成長可期。三星在其下一代高頻寬記憶體zHBM也與台積電組成戰略聯盟,以期強強聯手擴大HBM版圖。

三星第2季HBM市占率為33%,KB證券預測第4季將接近40%,這是因為第3季三星的HBM4銷售預期較前1季增逾3倍,HBM4有望佔今年下半年HBM總銷售60%。三星已向主要客戶提供HBM4E樣品,並已全面量產HBM4。

請繼續往下閱讀...

三星也公佈下一代高頻寬記憶體zHBM的開發藍圖。KB證券研究員李昌明(音譯,Lee Chang-min)指出,「改善散熱問題以及大幅提升頻寬的zHBM可以透過三星電子一站式解決方案,以及與台積電的戰略聯盟等多種方式提供」。

三星晶圓良率也有所改善,三星4奈米製程良率已逾80%、2奈米GAA良率也增加至逾70%。

李昌明說,「4奈米製程良率實際上逼近台積電的競爭水準,而2奈米製程也從年初的低於50%迅速提高;2奈米製程良率的提升有望在未來加速銷售成長,不僅提升三星代工績效,同時增進HBM基礎裸晶的競爭力」。

Many U.S. states pass data center moratorium bills AI industry development faces obstacles

In the United States, eight states including New York have passed data center moratorium bills due to public concerns about rising electricity prices due to data center power consumption. According to statistics, 75 data center construction plans were blocked in the first quarter of this year, involving a total amount of approximately US$130 billion, which may become a huge obstacle to the rapid development of the AI ​​industry.

Artificial intelligence promotes intelligent logistics: from warehousing robots to unmanned delivery vehicles, the Service Trade Fair will demonstrate how new technologies can improve efficiency

At the 2026 Service Trade Conference, reporters observed that artificial intelligence is changing the logic of traditional logistics operations. Warehousing robots can autonomously crawl shelves, robot dogs travel through venues, and unmanned delivery vehicles drive autonomously on mountain roads. They have been operating in rural Nanxiong, Guangdong for two months and have traveled a total of nearly 2,000 kilometers. China Post Guangzhou Postal Area Center uses intelligent management and control systems and embodied intelligent robots to relieve sorting pressure and achieve zero-congestion shifts. my country's express delivery business has ranked first in the world for 12 consecutive years. In the first half of the year, it exceeded 100 billion pieces nine days earlier than last year. The national "Logistics Network Construction Implementation Plan" has included "artificial intelligence + logistics" in the plan.
