    Abstract: Systems, methods, and apparatus including computer-readable mediums for managing block arrangement of super blocks in a memory such as NAND flash memory are provided. In one aspect, a memory controller for managing block arrangement of super blocks in a memory includes control circuitry coupled to the memory having at least two planes of physical blocks and configured to maintain block information of each individual physical block in the planes and combine one or more physical blocks from the planes to a super block based on the block information of the physical blocks in the planes.

    Abstract: A request is received to load a particular overlay segment from a secondary storage memory to a main memory for execution by a processor, wherein the particular overlay segment is absent from the main memory. A determination is made whether the main memory can receive the particular overlay segment. In response to determining that the main memory cannot receive the particular overlay segment, eviction strategy information about one or more existing overlay segments that are present in the main memory is obtained. Based on the eviction strategy information, at least one of the one or more existing overlay segments is selected for eviction from the main memory. The particular overlay segment is retrieved from the secondary storage memory. The at least one of the one or more existing overlay segments in the main memory that is selected for eviction is replaced with the particular overlay segment.

    Abstract: A memory controller managing a memory device receives a memory read command from a host device that is communicably coupled to the memory device. The memory device includes a storage memory comprising a first type of memory cells and a cache memory comprising a second type of memory cells. The memory controller determines, from the memory read command, a physical address of a target memory location in the storage memory indicated by the memory read command. The memory controller executes a read operation on the target memory location corresponding to the physical address. The memory controller determines a read attribute of the target memory location. Conditioned on determining that the read attribute satisfies one or more threshold conditions, the memory controller programs an entry in the cache memory with information corresponding to the target memory location.

    Abstract: The invention provides a memory device including a memory array, an internal memory, and a processor. The memory array stores node mapping tables for access data in the memory array. The internal memory includes a namespace table and an index table The processor obtains a data access command from a host device to determine whether a data of the data access command contains one of the NSIDs, assigns the at least one internal NSID to the data of the data access command according to the data access command in response to the data of the data access command that does not contain the namespace identifier, and, the processor manages the data with the internal NSID by the namespace table and the index table.

    Abstract: The invention provides a memory device including a memory array, an internal memory, and a processor. The memory array stores node mapping tables for access data in the memory array. The internal memory includes a cached mapping table area and has a root mapping table. The processor determines whether a first node mapping table of the node mapping tables is temporarily stored in the cached mapping table area according to the root mapping table. In response to the first node mapping table is temporarily stored in the cached mapping table area, the processor accesses data according to the first node mapping table in the cached mapping table area, marks the modified first node mapping table through an asynchronous index identifier, and writes back the modified first node mapping table from the cached mapping table area to the memory array.
