Self-repairing memory
Abstract:
A memory array has a plurality of rows including a plurality of memory words. Each first bit of a plurality of first bits is associated with a memory word of the each row. A state of the each first bit indicates whether the associated memory word has had an error. Each redundancy row of a plurality of redundancy rows includes a plurality of redundancy words. Each redundancy word is associated with a memory word. A corrected data cache has at least one repair word configured to store corrected data and at least one status bit associated with the at least one repair word, the status bit indicating whether the corrected data stored in the repair word is a pending repair. The corrected data cache is configured to write the corrected data stored in the repair word to at least one of a counterpart memory word or a counterpart redundancy word.
