Voltage based combining of block families for memory devices

A method comprising:

• identifying, by a processor, a first block family comprising a first set of blocks, wherein the first block family comprises a plurality of blocks that have been programmed within at least one of a specified time window or a specified temperature window;
• identifying a second block family comprising a second set of blocks;
• and
• responsive to a determining that a threshold criterion is satisfied, combining the first block family and the second block family by appending, to first block family metadata of the first block family, a record referencing the second set of blocks.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device operatively coupled to a memory device, perform operations comprising:

• identifying a first block family comprising a first set of blocks, wherein the first block family comprises a plurality of blocks that have been programmed within at least one of a specified time window or a specified temperature window;
• identifying a second block family comprising a second set of blocks;
• and
• responsive to a determining that a threshold criterion is satisfied, combining the first block family and the second block family by appending, to first block family metadata of the first block family, a record referencing the second set of blocks.
