Abstract: The present disclosure provides a memory management method and a memory controller for a storage device configured with a memory module. The method obtains a continuity status table, identifies a target mapping table and obtains its continuity status based on a data access command and the continuity status table, determines whether to use a contiguous segment mapping table based on the continuity status, loads the contiguous segment mapping table to a buffer memory if determined to use it, or loads the target mapping table to the buffer memory if determined not to use it, and obtains a physical address based on the loaded mapping table to access the memory module. The present disclosure dynamically selects the optimal mapping table processing approach by evaluating the contiguity of physical addresses in the mapping table, effectively improving data access performance and optimizing buffer memory utilization efficiency.
