Abstract:
An electronic fuse system and method are disclosed employing a fuse ROM having one or more blocks of memory. Each block of memory comprises a plurality of words with at least one word of the plurality of words containing security bits associated with a respective block. An electronic fuse controller is in communication with the fuse ROM and one or more external devices that are configured to request one or more words that reside in the fuse ROM from the electronic fuse controller. At least one security register includes indication bits that provide an indication whether security bits have been obtained for a respective block of memory of the fuse ROM after a power down and power up cycle. The electronic fuse controller provides the requested word if an indication bit associated with the block of memory is set.
