Abstract
A buried fuse reading device includes at least one buried fuse and at least one sense amplifier sensing a condition of the buried fuse. A validation circuit in the buried fuse reading device detects and indicates when output from the sense amplifier is valid.
Claims16
A buried fuse reading device, comprising:
- at least one buried fuse;
- at least one sense amplifier sensing a condition of the buried fuse;
- and
- a validation circuit detecting and indicating when output from the sense amplifier is valid.
1 more element
A buried fuse reading device, comprising:
- at least one buried fuse;
- at least one sense amplifier sensing a condition of the buried fuse;
- and
- a validation circuit dynamically adjusting a validation point of the sense amplifier based on operating conditions, the validation point being a point in time when output from the sense amplifier is considered valid.
1 more element
A buried fuse reading device, comprising:
- at least one buried fuse;
- at least one sense amplifier sensing a condition of the buried fuse;
- and
- a tracking circuit tracking operation of the sense amplifier such that the tracking circuit indicates when the sense amplifier has sufficiently settled on a sensed condition of the buried fuse.
