摘要:
Circuits, methods, and devices for protecting against accidental fuse programming are discussed herein. For example, a fuse circuit may include a first switch electrically connected to a first point, a fuse electrically connected in series with the first switch, a first biasing circuit to control the first switch to enable programming of the fuse in response to a fuse programming event, a second switch electrically connected in series with the fuse between the fuse and a second point, and a second biasing circuit to control the second switch to enable programming of the fuse in response to the fuse programming event.
