Performing selective copyback in memory devices

A method, comprising:

• determining, by a processor, a data validity metric value with respect to a source set of memory cells of the memory device;
• determining whether the data validity metric value satisfies a first threshold criterion;
• responsive to determining that the data validity metric value satisfies the first threshold criterion, performing a data integrity check on the source set of memory cells to obtain a data integrity metric value;
• determining whether the data integrity metric value satisfies a second threshold criterion;
• responsive to determining that the data integrity metric value satisfies the second threshold criterion, performing an error handling operation on data from the source set of memory cells to generate corrected data;
• and
• copying the corrected data to a destination set of memory cells.

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

• determining a data validity metric value with respect to a source set of memory cells of the memory device;
• determining whether the data validity metric value satisfies a first threshold criterion;
• responsive to determining that the data validity metric value satisfies the first threshold criterion, performing a data integrity check on the source set of memory cells to obtain a data integrity metric value;
• determining whether the data integrity metric value satisfies a second threshold criterion;
• and
• responsive to determining that the data integrity metric value fails to satisfy the second threshold criterion, causing the memory device to copy data from the source set of memory cells to a destination set of memory cells of the memory device.
