韓媒:美光緊追+南亞科差距縮,動搖三星記憶體一哥地位

三星電子灑錢投資晶圓代工和人工智慧(AI)半導體,全力搶攻相關市場,同時對記憶體部門的投資卻相對保守。韓媒指稱,競爭對手技術躍進,動搖三星的記憶體龍頭地位。
韓媒 Pulse、BusinessKorea 報導,三星稱霸全球記憶體市場 29 年之久,但近年來市佔不斷下滑。TrendForce 數據顯示,三星 DRAM 市佔 2016 年高達 48%,2020 年降至 43.1%,去年第四季更跌至 42.1%。NAND flash 方面,三星市佔也從 2017 年 40% 以上,2020 年第四季降至 33.4%。
三星原本持續技術領先,在業界無人能敵,但是近來對手技術大幅提升,削弱了三星的領導地位。去年 11 月,美國業者美光(Micron)搶在三星之前,率先發表全球首見的第七代 3D NAND flash 共 176 層。三星仍在生產第六代 3D NAND flash,第七代預定要 2021 年下半才會問世。
不只如此,美光 DRAM 領域也快速追上三星。美光一如三星,已量產 10 奈米 DRAM,正使用極紫外光(EUV)微影機台研發次世代 DRAM 製程,目標 2021 年上半發表首款 EUV DRAM。
另外,美光打算併購 NAND flash 二哥鎧俠(Kioxia),如果兩廠順利合併,美光 NAND flash 市佔將追上三星。
不只美光,台廠南亞科也縮小和三星的技術差距。南亞科正加速研發,要用 EUV 技術生產晶片。中廠則在政府金援下迅速升級技術。
