  • Patent number: 10566070
    Abstract: A method of operating an electronic device includes: precharging a fuse read node to an intermediate voltage less than an input voltage, wherein the fuse read node connects a fuse array and a fuse read circuit, the fuse array including a fuse cell configured to store information and the fuse read circuit configured to read the stored information; connecting the fuse cell to the fuse read node for reading the information; and determining, with the fuse read circuit, the information from the fuse cell based on changes to the intermediate voltage at the fuse read node.

  • Patent number: 10304554
    Abstract: A circuit may include a first switch to pre-charge a first voltage line to a first voltage for a first amount of time, such that the first voltage is an opposite polarity as compared to a second voltage coupled to the first voltage line when a first fuse is blown. The circuit may also include a second switch to pre-charge a second voltage line to a third voltage for the first amount of time, such that the third voltage is an opposite polarity as compared to a fourth voltage coupled to the second voltage line when a second fuse is blown. The circuit also includes a latch circuit to amplify a first voltage signal present on the first voltage line and amplify a second voltage signal present on the second voltage line after the first amount of time expires.
