Abstract
Systems and methods for managing regular maintenance operations in combination with infrequent extended maintenance operations in a non-volatile memory are disclosed. The method may include executing portions of the extended maintenance over the course of multiple regular maintenance operations. A memory system may include non-volatile memory and a controller configured to execute one or more of the steps of selecting a previously programmed source block for an extended maintenance operation, sequentially selecting a plurality of previously programmed blocks for regular maintenance operations and dividing execution of the extended maintenance operation up such that the extended maintenance operation is completed in parts across the plurality of regular maintenance operations.
