1. An integrated circuit including an electrically resettable fuse device, the electrically resettable fuse device comprising:

  • a plurality of resettable fuse modules coupled in parallel, each resettable fuse module including a fuse element characterized by a first and a second impedance states, the plurality of resettable fuse modules are configured such that;

    when the fuse element is in the first impedance state, and a current flowing through each fuse element in a first direction exceeds a current limit, the fuse element enters into the second impedance state; and

    when the fuse element is in the second impedance state and, in response to a global reset signal and a local reset signal, a current is applied to the fuse element in a second direction opposite the first direction, the fuse element is reset to the first impedance state.
