ABSTRACT:
A circuit (10) for storing and retrieving data is provided. Circuit (10) stores data on a data fuse (20). The values of the stored data may be established by comparing the data fuse (28) with a test fuse (22) using a storage and sensing circuit (12). The value of the data fuse (20) may be set by a fuse setting circuit (14). Additionally, a value may be substituted for the data fuse (20) using a flip flop (16) and an output logic circuit (18).
