OPTIMIZING fuseROM USAGE FOR MEMORY REPAIR |
摘要 |
A memory repair system in an integrated circuit (IC) that optimizes the fuseROM used for memory repair. The IC includes a plurality of memory wrappers. Each memory wrapper includes a memory block with a fuse register and a bypass register. The bypass register has a bypass data that indicates a defective memory wrapper of the plurality of memory wrappers. A fuseROM controller is coupled to the plurality of memory wrappers. A memory bypass chain links the bypass registers in the plurality of memory wrappers with the fuseROM controller. The fuseROM controller loads the bypass data in the memory bypass chain. A memory data chain links the fuse registers in the plurality of memory wrappers with the fuseROM controller. The memory data chain is re-configured to link the fuse registers in a set of defective memory wrappers of the plurality of memory wrappers responsive to the bypass data loaded in the memory bypass chain. |
