ABSTRACT:
In a memory array having redundant columns, a scheme allows defective cells to be individually remapped to redundant cells in a redundant column. Redundant cells in one redundant column replace defective cells in multiple non-redundant columns. Remapping is done as part of initial test and configuration. Specific hardware can be used for the scheme or firmware in the memory controller can implement the scheme.
