Patent ID: 10490294

Abstract:
Systems and methods are directed to an integrated circuit to sense a state of a fuse having one of a blown state and an unblown state. The integrated circuit includes a fuse sensing circuit having an input and a plurality of outputs, the input being configured to receive a sense signal having a first state and a second state, and the plurality of outputs including a first output to connect to a first contact of the fuse, a second output to provide a first signal indicative of the state of the fuse, and a third output to provide a second signal indicative of the state of the fuse, the fuse sensing circuit being configured to provide the first and second signals responsive to a change in state of the sense signal, and a latch circuit having a first input to receive the first signal, a second input to receive the second signal, and an output to provide an output signal indicative of the state of the fuse, the latch circuit being configured to store and maintain a value of the output signal.
