摘要:
A multiple trip point fuse latch device and method is disclosed. Multiple read inputs to a fuse latch enable the altering of the resistive trip point of the fuse latch. A multiple trip point fuse latch may be combined with a slave latch to form a master-slave flip-flop, and multiple master-slave flip-flops may be connected in series to form a shift register. Changing the trip point permits the use of a test procedure that may analyze the margins of a fuse latch during the fuse read operation.
