Managing partial superblocks in a NAND device

A method for managing partial superblocks in a NAND device, the method comprising:

• calculating a set of superblock candidates, a superblock comprising a set of blocks that share a same position in each plane in each die of a NAND array of the NAND device, each plane having at most one block from the set of blocks,
• calculating a set of partial super block candidates, a partial superblock candidate being a superblock candidate that has at least one plane that has a bad block;
• obtaining a partial superblock use classification, wherein the partial superblock use classification includes a set of groups, a member of the set of groups including an allocation of partial superblocks to a set of the class of data, and wherein a group in the set of groups allocates partial superblocks to store the first-level translation table, the firmware, and the bad-block-table classes of data;
• establishing superblocks for the NAND device by using members of the set of superblock candidates after removing the set of partial superblock candidates from the set of superblock candidates;
• and
• establishing partial superblocks for classes of data in the NAND device according to the partial superblock use classification.

At least one non-transitory machine readable medium including instructions for managing partial superblocks in a NAND device, the instructions, when executed by processing circuitry, cause the processing circuitry to perform operations comprising:

• calculating a set of superblock candidates, a superblock comprising a set of blocks that share a same position in each plane in each die of a NAND array of the NAND device, each plane having at most one block from the set of blocks;
• calculating a set of partial super block candidates, a partial superblock candidate being a superblock candidate that has at least one plane that has a bad block;
• obtaining a partial superblock use classification, wherein the partial superblock use classification includes a set of groups, a member of the set of groups including an allocation of partial superblocks to a set of the class of data, and wherein a group in the set of groups allocates partial superblocks to store the first-level translation table, the firmware, and the bad-block-table classes of data;
• establishing superblocks for the NAND device by using members of the set of superblock candidates after removing the set of partial superblock candidates from the set of superblock candidates;
• and
• establishing partial superblocks for classes of data in the NAND device according to the partial superblock use classification.
