Claim 0:
1. A method, comprising:
receiving a memory access command from a host and determining that a criteria involving a memory device is met, wherein the criteria includes a number of program-erase cycles (PECs) for at least one memory die of a number of memory dice of the memory device is above a threshold quantity;
performing a defect scan involving the number of memory dice of the memory device in response to receiving the memory access command and the criteria being met by scanning each of the number of memory dice on an entire die-by-entire die basis;
determining, as part of performing the defect scan, whether at least one memory die of the memory device has experienced degradation; and
responsive to determining that the at least one memory die has experienced degradation, refraining from fulfilling the memory access command to read data written to the at least one memory die that has experienced the degradation, performing a recovery operation for user data on the at least one memory die requested by the memory access command, and transfer the recovered user data to the host to fulfill the memory access command.
