Abstract:
Methods for providing redundancy in a memory include mapping a portion of first data associated with an address of the memory determined to indicate a defective memory cell to an address of a redundant area of the memory array, and writing second data to the memory array, wherein a portion of the second data is written to a column of the memory array associated with the address of the memory determined to indicate a defective memory cell for the first data. Apparatus include memory control circuitry configured to select a portion of data for mapping to a different address in response to an address indicating a defective memory cell, and further configured to select a different portion of data for a particular row than for a different row, wherein the particular row and the different row are associated with the same columns of the memory array.
