認長鑫4F²技術是「紙老虎」 分析師:2原因使中國競爭威脅被誇大

Quick Look

長鑫存儲宣稱在4F²架構上取得關鍵進展,並計畫年底前推出新晶片,但華爾街分析師卡希迪認為美光投資人反應過度,因技術量產與良率不明,長鑫可能只是「紙老虎」,不會對美光或SK海力士構成重大威脅,儘管此言論已引發全球記憶體類股恐慌性拋售。

Why It Matters

長鑫存儲為中國主要DRAM製造商,曾受美國制裁限制取得先進光刻機,其宣稱的4F²架構被視為潛在突破點,但量產與良率一直是業界關注焦點。

〔編譯魏國金/台北報導〕《Investor's Business Daily》14日報導,一名華爾街分析師認為,美光投資人對於中國DRAM巨頭長鑫存儲在記憶體領域取得「4F²架構關鍵進展」的反應過度,因為相關技術的量產與良率不明,長鑫充其量是「紙老虎」,不會對美光等記憶體大廠構成重大挑戰。美光股價已連日下跌。

長鑫總裁曹侃鈺上週末在上海舉行的一場產業會議上表示,計畫推出一款可將更多算力整合至單一元件的新型晶片。他指出,為資料中心伺服器打造的該款晶片稱為4F²架構設計,預計今年底前推出。

請繼續往下閱讀...

如果長鑫成功達到4F²技術門檻,這意味儘管美國制裁,阻止中企取得艾司摩爾(ASML)的頂尖機台,長鑫的技術進展仍領先三星與SK海力士,因為這兩家記憶體巨擘預計2028年才推出4F²架構設計。

儘管曹侃鈺沒有提供更多細節,不過該言論在廣泛報導後引發全球記憶體類股恐慌性拋售。美光14日早盤下跌近2%,過去5個交易日已跌13.16%。在韓國股市,SK海力士5個交易日跌17.88%、三星電子跌14%。

羅森布拉特證券(Rosenblatt Securities)分析師卡希迪(Kevin Cassidy)指出,這項引發記憶體類股拋售的消息「誇大了」。

他在13日晚間發布的客戶報告說,「該反應誇大了短期的競爭力威脅,忽略了正在重塑DRAM的結構性改變」。

他稱長鑫是「紙老虎」,不會對美光或SK海力士構成重大威脅。他重申,對美光與SK海力士仍給予買進評級,並表示,長鑫距4F²架構晶片的量產以及良率還有一段長路要走。

卡希迪指出,「長鑫的簡報並未確立製造良率或晶圓量產。新架構可能面臨巨大的初期良率挑戰,沒有這些資訊揭露,產品推出目標所提供的競爭力與量產經濟效益十分有限」。

US inflation is hard to come down! CPI increased by 3.7% year-on-year in September, higher than expected

The U.S. Bureau of Labor Statistics announced that the CPI increased by 3.7% in September, higher than market expectations of 3.6%. The main driver is the surge in energy prices (especially gasoline and fuel oil), and the core CPI is also higher than expected, indicating that inflationary pressure continues, and the market expects the probability of the Federal Reserve to raise interest rates by the end of the year.
