Abstract
Self-test circuits of memory devices disclosed herein may include circuitry that adjusts the correspondence between logical and physical addresses to match pre-repair mapping of memory locations. That is, if a memory device has been repaired by remapping logical addresses to new physical addresses, the circuitry of the test circuit restores the pre-repair mapping of the memory device in some examples. In some examples, an unused global column redundancy data path may be repurposed to provide repair information to the self-test circuit to implement the pre-repair mapping.
