In computing, an eFuse (electronic fuse) is a microscopic fuse put into a computer chip. This technology was invented by IBM in 2004 to allow for the dynamic real-time reprogramming of chips. In the abstract, computer logic is generally "etched" or "hard-wired" onto a chip and cannot be changed after the chip has finished being manufactured. By utilizing a set of eFuses, a chip manufacturer can allow for the circuits on a chip to change while it is in operation.

  • En informatique, un eFuse (fusible électronique) est un fusible microscopique inséré dans une puce informatique. Cette technologie a été inventée par IBM en 2004 pour permettre la reprogrammation dynamique en temps réel des puces. Abstraitement, la logique informatique est généralement "gravée" ou "câblée" sur une puce et ne peut pas être modifiée une fois que la fabrication de la puce est terminée. En utilisant plusieurs eFuse, un fabricant de puces peut permettre aux circuits d'une puce de changer pendant son fonctionnement. (fr)
  • eFUSE是IBM開發的技術,於2004年面世,可以動態實時地重新修改積體電路中的程式。簡單來說,積體電路中的程式在工廠生產時就已蝕刻在積體電路中,在積體電路出廠後無法再修改。但透過eFUSE的技術,積體電路生產商可以在其運作時再調整積體電路中的電路。 此技術主要的應用是在晶片上的性能調校。若有某個子系統不動作、回應時間太長,或是消耗的電過大,可以熔斷eFUSE來調整其性能。 另一個用途是防止降級設備韌體行為,任天堂的Nintendo Switch和微軟的Xbox 360在安裝新韌體之前就會熔斷一定數量的eFUSE,預計熔斷的eFUSE數量取決於現有安裝硬體的型號和韌體版本。如果有太多的eFUSE熔斷(這意味著安裝固件比現有固件更舊),引導程式將死機,防止繼續安裝。在成功升級韌體版本之後,系統將熔斷所需eFUSE,以匹配預期的數量。 (zh)
  • Na computação, eFUSE é uma tecnologia criada pela IBM que permite a reprogramação dinâmica em tempo real de chips de computador. Abstratamente, a lógica do computador é em geral "esboçada" ou "codificada" em um chip e não pode ser alterada uma vez que o chip é fabricado. Utilizando um eFUSE (ou, de forma mais realista, uma série de eFUSEs individuais), o fabricante de um chip pode permitir que os circuitos de um chip mudem enquanto ele estiver em operação. (pt)

Utilizando um eFUSE (ou, de forma mais realista, uma série de eFUSEs individuais), o fabricante de um chip pode permitir que os circuitos de um chip mudem enquanto ele estiver em operação. A finalidade primária dessa tecnologia é permitir o ajuste interno de desempenho no chip. Caso certos subsistemas falhem, demorem muito para responder, ou estejam consumindo muita força, o chip pode instantaneamente mudar seu comportamento "detonando" um eFUSE. (pt)
