Balancing wear across multiple reclaim groups

A method comprising:

• grouping a set of memory components into a plurality of reclaim groups (RGs), each RG of the plurality of RGs comprising a subset of reclaim units (RUs);
• receiving, from a host system, a request to program a set of data into a first RG of the plurality of RGs, the request specifying the first RG of the plurality of RGs in which to program the set of data;
• comparing a first program-erase count (PEC) of the first RG with a second PEC of a second RG of the plurality of RGs;
• performing wear leveling operations for the set of data requested to be programmed into the first RG using one or more memory components associated with the second RG based on a result of comparing the first PEC of the first RG with the second PEC of the second RG;
• based on performing the wear leveling operation, programming the set of data into one or more of the subset of RUs of the second RG instead of the subset of RUs of the first RG specified in the request from the host system;
• wherein the operations comprise:
• enlarging a size of an individual RU of the subset of RUs of the first RG by donating a portion of a second RU of the subset of RUs of the second RG to the individual RU.

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

• grouping a set of memory components into a plurality of reclaim groups (RGs), each RG of the plurality of RGs comprising a subset of reclaim units (RUs);
• receiving, from a host system, a request to program a set of data into a first RG of the plurality of RGs, the request specifying the first RG of the plurality of RGs in which to program the set of data;
• comparing a first program-erase count (PEC) of the first RG with a second PEC of a second RG of the plurality of RGs;
• performing wear leveling operations for the set of data requested to be programmed into the first RG using one or more memory components associated with the second RG based on a result of comparing the first PEC of the first RG with the second PEC of the second RG;
• based on performing the wear leveling operation, programming the set of data into one or more of the subset of RUs of the second RG instead of the subset of RUs of the first RG specified in the request from the host system;
• wherein the operations comprise:
• enlarging a size of an individual RU of the subset of RUs of the first RG by donating a portion of a second RU of the subset of RUs of the second RG to the individual RU.
