美光將繼續推進 6F² DRAM,並投入 3D DRAM;這是公司的技術路線選擇,並不代表競爭對手的 4F² 方案一定行不通。
Why did Micron Technology decide not to commercialize 4F² DRAM while Samsung Electronics, SK hynix and CXMT continue developing it, and howMicron argues that DRAM density depends on practical manufacturing constraints, not cell footprint alone.

美光沒有退出先進 DRAM 的競賽,而是選擇另一條提高記憶體密度的路。公司認為,4F² 設計雖然能縮小記憶體單元的名目面積,但電容間距、微縮限制、成本與製程複雜度,可能讓理論上的優勢難以落實到量產產品。美光因此打算繼續推進 6F² DRAM,並開發 3D DRAM。 235
4F² 面積較小,為何不一定代表密度更高?
4F² 和 6F² 指的是單一記憶體單元所占的面積。若 F 的尺度相同,4F² 在數學上比 6F² 小三分之一;不過,這比較的是單元的名目面積,不等於整顆 DRAM 晶片最後能達到的實際密度也提高三分之一。 513
在 2026 年 10 月 21 日的技術網路研討會上,美光總裁暨技術與產品長 Scott DeBoer 回應 UBS 分析師 Tim Arcuri 提問時表示,電容之間的間距,也就是電容間距(pitch),是影響 DRAM 密度的重要限制。在美光的評估中,單靠縮小單元布局,未必能帶來表面上看起來那麼大的密度提升。 510
