Abstract
Multiple fuse decompression serial bitstreams support an auxiliary fuseblow capability utilizing on-chip storage and providing a composite capability of embedded memory address/data failure information. A multiple repair capability has an improved compression algorithm to compress fuse data with system level soft-set redundancy, and lends itself to self-repair design, and to provide repairs for temperature sensitive fails. An instruction based tester interface in a fuse control provides shift loaded instructions in which the sequence of test and fuse repair operations is variable to provide flexibility in the manufacturing, test and repair operations.
