Selective relocation of data of a subset of a data block based on distribution of reliability statistics

A system comprising:

• a memory component comprising a plurality of data blocks each comprising a plurality of memory cells configured to store data;
• and
• a processing device operatively coupled to the memory component, the processing device to perform operations comprising:
• sampling a set of memory cells of a respective plurality of memory cells of a data block of the plurality of data blocks of the memory component;
• generating a distribution statistic for the data block based on a reliability statistic for each of the sampled set of memory cells;
• determining, based on the distribution statistic, whether a read disturb stress is uniformly distributed or non-uniformly distributed across the data block;
• and
• responsive to determining that the read disturb stress is non-uniformly distributed across the data block, relocating a first subset of the data block to another data block of the plurality of data blocks of the memory component, wherein the first subset of the data block is associated with a higher concentration of read disturb stress than other subsets of the data block.

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

• sampling set of memory cells in a data block of a memory component;
• generating a distribution statistic for the data block based on a reliability statistic for each of the sampled set of memory cells;
• determining, based on the distribution statistic, whether a read disturb stress is uniformly distributed or non-uniformly distributed across the data block;
• and
• responsive to determining that the read disturb stress is non-uniformly distributed across the data block, relocating a first subset of the data block to another data block of the memory component, wherein the first subset of the data block is associated with a higher concentration of read disturb stress than other subsets of the data block.
