Abstract
Embodiments of the disclosure are drawn to apparatuses and methods for automatic soft post-package repair (ASPPR). A memory may receive a row address along with a signal indicating an ASPPR operation, such as a bad page flag being set. A word line engine generates a physical address based on the row address, and ASPPR registers stores the physical address. The time it takes from receiving the row address to storing the physical address may be within the timing of an access operation on the memory such as tRAS. The row address may specify a single page of information. If the bad page flag is set, then a subsequent PPR operation may blow fuses to encode the physical address stored in the ASPPR registers.
