Abstract
Techniques are provided for storing a row address of a defective row of memory cells to a bank of non-volatile storage elements (e.g., fuses or anti-fuses). After a memory device has been packaged, one or more rows of memory cells may become defective. In order to repair (e.g., replace) the rows, a post-package repair (PPR) operation may occur to replace the defective row with a redundant row of the memory array. To replace the defective row with a redundant row, an address of the defective row may be stored (e.g., mapped) to an available bank of non-volatile storage elements that is associated with a redundant row. Based on the bank of non-volatile storage elements the address of the defective row, subsequent access operations may utilize the redundant row and not the defective row.
