1. A method, comprising:
dynamically forming at least a portion of a first superblock using a first subset of blocks from at least one memory die of a memory sub-system, wherein at least one block from each of a plurality of planes of the at least one memory die is not included in the first subset of blocks; and
dynamically forming at least a portion of a second superblock using a second subset of blocks from the at least one memory die of the memory sub-system, wherein at least one block from each of a plurality of planes of the at least one memory die is not included in the second subset of blocks and at least one block of at least the portion of the second superblock is not in a same plane among the plurality of planes of the at least one memory die as a block that is included in at least the portion of the first superblock, and wherein forming the first superblock, the second superblock, or both, reduces a percentage of overprovisioned superblocks associated with the memory sub-system.
