Abstract
The invention provides a method and an apparatus for enabling a user to determine whether a defective location in a memory device of an integrated circuit (IC) has been remapped to a location in a redundant memory portion of the memory device. Users are provided with the ability to observe the remapping, and preferably, to determine which locations in the memory device have been remapped. The memory device includes remapping observation logic that causes bits associated with remapping to be output from the memory device. Preferably, a computer receives the remapping bits and displays a description of any remapping on a display monitor. Therefore, not only is a user able to determine whether remapping has occurred, but also which locations in the memory device have been remapped.
