Abstract
A memory device includes a memory cell array and a repair circuit configured to perform a repair operation and output a dirty signal to an external destination external to the memory device. The repair circuit further performs selecting a first redundancy address of the redundancy memory cells instead of a first fail address of the first failed memory cell, storing a first redundancy mapping for the first fail address to the first redundancy address, and in response to determining a second fail address of a second failed memory cell matches the first fail address, ignoring the first redundancy mapping, and outputting a dirty signal causing a second redundancy mapping to map the first fail address to a second redundancy address different from the first redundancy address of the redundancy memory cells.
