Abstract
Systems and methods for managing programming schedules of programming host data and maintenance operations in a non-volatile memory are disclosed. A method includes determining multiple integer interleave ratios of host data writes to relocation writes of previously programmed data when non-integer interleave situations are determined for a previously programmed source block selected for a maintenance operation. The method may include writing the host data and relocating previously programmed data in groups of operations having these determined integer interleave ratios. A memory system may include non-volatile memory and a controller configured to identify non-integer interleave situations and then break up the host data and relocation data writes into multiple interleave groups each having a different integer interleave ratio such that a whole number of write operations for the interleave groups may be carried out to achieve more precise control and efficiency in maintenance operations.
