Original Abstract Submitted
Aspects of the present disclosure configure a memory sub-system controller to balance program-erase count (PEC) across multiple reclaim groups of a memory sub-system. The controller groups 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). The controller receives a request to program a set of data into a first RG of the plurality of RGs and compares a first PEC of the first RG with a second PEC of a second RG of the plurality of RGs. The controller performs 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.
