Abstract
A processing device in a memory system detects a data loss occurrence in a block of a memory component. The processing device further designates the block as a quarantined block, performs a stress test on the block, and depending on whether the stress test on the block satisfies a testing criterion, either designates the block as usable by the memory component or retires the block of the memory component.
