Abstract:
Apparatuses and methods for post package repair are disclosed. An apparatus can include memory cells in a package. A storage element can store information responsive to a post-package repair mode being activated. The information can identify an address mapped to a portion of the memory cells to be repaired. The storage element can store the information responsive to data received from nodes of the package. A walking token circuit can interrogate the information stored in the storage element in a serial fashion responsive to the post-package repair mode being activated. A mapping circuit can remap, responsive to the interrogation, the address to be repaired to another portion of the memory cells.
