摘要：
Fuse macros of identical number of pages are serially arranged to form the same number of fusebay pages each having a length equal to the sum of the respective fuse macro page lengths. Each fuse macro has an enable latch configured to allow activation of one fuse macro at a time. A fusebay control device connected to a repair register may store data in and retrieve data from the fusebay. Next available fuse location is determined in programming mode so that data from a next repair pass may start where the last data ended.
