eFUSE
From Infogalactic: the planetary knowledge core
Lua error in package.lua at line 80: module 'strict' not found. In computing, eFUSE is a technology invented by IBM which allows for the dynamic real-time reprogramming of computer chips. Speaking abstractly, computer logic is generally "etched" or "hard-coded" 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.
The primary application of this technology is to provide in-chip performance tuning. If certain sub-systems fail, or are taking too long to respond, or are consuming too much power, the chip can instantly change its behavior by "blowing" an eFUSE.

- Sony/Toshiba/IBM Cell used in PlayStation 3
- IBM/Microsoft Xenon CPU in the Xbox 360 game console.
- TI OMAP3-based mobile phones and other devices[1][2]
- Samsung KNOX-enabled devices (KNOX waranty void bit)[3]
