Block family combination and voltage bin selection

A system comprising:

• a memory device;
• and
• a processing device coupled to the memory device, the processing device to perform operations comprising:
• determining values of a data state metric for each of a first plurality of block families associated with a first voltage bin, wherein each block family comprises a plurality of pages of a memory device that have been programmed within a corresponding time window, and wherein each measurement value corresponds to a state of data for a particular block family of the first plurality of block families;
• responsive to determining, based on the values of the data state metric for each of the first plurality of block families, that a voltage for each of the first plurality of block families satisfies a block family combination criterion, merging each block family of the first plurality of block families;
• responsive to determining that a continuation scan criterion is satisfied, selecting a second plurality of block families associated with the first voltage bin;
• and
• performing a calibration scan for each block family of the second plurality of block families.

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

• selecting a plurality of block families associated with a first voltage bin, wherein each block family comprises a plurality of pages of a memory device that have been programmed within a corresponding time window, and wherein the plurality of block families comprises a first block family and a second block family;
• determining values of a data state metric for each of the plurality of block families;
• determining, based on the values of the data state metric, a first voltage for the first block family and a second voltage for the second block family;
• and
• responsive to determining that a difference between the first voltage and the second voltage satisfies a block family combination criterion, merging the second block family with the first block family.
