Abstract:
One or more blocks from a pool of storage area blocks of the memory component are allocated to a first set of purposed blocks. First write operations are performed to write first data to first data stripes at user blocks of the memory component. Whether the blocks in the first set of purposed blocks satisfy a condition indicating that the first set of purposed blocks are to be retired is determined. Responsive to the blocks in the first set of purposed blocks satisfying the condition, one or more other blocks from the pool of storage area blocks of the memory component are allocated to a second set of purposed blocks. Second write operations are performed to write second data to second data stripes at the user blocks of the memory component.
