Abstract:
1. An apparatus comprising: a first control circuit configured to generate a first control signal in response to (i) an input signal from a fuse and (ii) one or more read signals; a latch circuit configured to change states in response to said first control signal; a second control circuit configured to change the state of said latch circuit in response to (i) said one or more read signals and (ii) one or more set signals; a flip-flop configured to capture the state of said fuse in response to changing the state of said latch circuit with said first control circuit or said second control circuit; and a third control circuit configured to (i) capture data from a previous scan of said flip-flop and (ii) set said latch circuit to one or more states in response to one or more write signals and said one or more read signals.
