Memories and methods for replacing memory sections of a main memory array by mapping memory addresses for an entire main memory section to at least one memory section of a redundant memory array. One such memory includes a fuse block having programmable elements configured to be programmed to identify main memory sections to be mapped to redundant memory sections of the redundant memory array. The memory further includes a redundant memory logic circuit coupled to the redundant memory array and the fuse block. The redundant memory logic is configured to map the memory for a main memory section identified in the fuse block to at least one of the redundant memory sections of the redundant memory array.
