Life time extension of memory device based on rating of individual memory units

A method comprising:

• obtaining respective life expectancies of a first data unit and a second data unit of a memory device;
• determining a longest life expectancy between the first data unit and the second data unit;
• calculating, based on a difference between the longest life expectancy and the respective life expectancies of the first data unit and the second data unit, a first initial age value corresponding to the first data unit and a second initial age value corresponding to the second data unit, wherein the first initial age value and second initial age value represent cycle counts at which point a media management operation is to be performed;
• identifying a lower one of the first initial age value and the second initial age value;
• performing, at a first time, a first media management operation on one of the first data unit or the second data unit associated with the lower one of the first initial age value and the second initial age value;
• and
• performing, at a second time, a second media management operation on the first data unit and the second data unit.

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

• obtaining respective life expectancies of a plurality of data units of a memory device;
• determining a longest life expectancy between the plurality of data units;
• calculating, based on a difference between the longest life expectancy and the respective life expectancies of the plurality of data units, respective initial age values corresponding to each of the plurality of data units, wherein an initial age value represents a cycle count at which point a media management operation is to be performed on a corresponding data unit;
• and performing, based on the initial age value, a media management operation on a subset of the plurality of data units associated with initial age values that match a current cycle count of the memory device.
