Abstract
Embodiments of the disclosure are drawn to apparatuses and methods for soft post-package repair (SPPR). After packaging, it may be necessary to perform post-package repair operations on rows of the memory. During a scan mode of an SPPR operation, addresses provided by a fuse bank may be examined to determine if they are open addresses or if the bad row of memory is a redundant row of memory. The open addresses and the bad redundant addresses may be stored in volatile storage elements, such as in latch circuits. During a soft send mode of a SPPR operation, the address previously associated with the bad row of memory may be associated with the open address instead, and the address of the bad redundant row may be disabled.
