ABSTRACT:
In a non-volatile memory array, scheduling of reclaim operations to occur before a shortage of erased blocks arises avoids extended periods of reclaim that could exceed a time limit. A memory controller uses information regarding the data stored in the memory array to estimate the additional host data that may be programmed and the reclaim operations to be performed and schedules the reclaim operations to be evenly distributed between write operations until the memory is full.
