Abstract
A memory system includes a main memory array, a redundant memory array, and a content addressable memory (CAM). The CAM includes a plurality of entries, wherein each entry includes a plurality of column address bits and a plurality of maskable row address bits. When an access address for a memory operation matches an entry of the CAM, the memory system is configured to access the redundant memory array to perform the memory operation.
