A memory management component can track the amount of time between erase cycles for a particular memory region, and can manage memory region such that the regions are given sufficient time to rest and recover, or are given at least as much rest time as is practical, before being subject to an erase cycle. A reclamation management component can reclaim memory region that have invalid data stored therein, and can reclaim regions on a just-in-time basis when practical, and can determine which regions to reclaim based on various factors, such as the amount of time since a region was last erased, and the number of programming errors associated with a region. The memory management component can thereby optimize the useful life, minimize or reduce loss of margin in memory regions, and minimize or reduce programming errors of memory regions, of non-volatile (e.g., flash) memory.
