Abstract
According to one aspect of the present disclosure, a memory system is provided. The memory system may include at least one non-volatile memory device and a memory controller coupled to the at least one non-volatile memory device. A multi-level mapping table may be stored in the memory device. The multi-level mapping table may be configured to implement mapping from a logical address to a physical address. The memory controller may include a buffer. A portion of the multi-level mapping table may be stored in the buffer. The memory controller may be configured to perform a random read operation on the data stored in the memory device. In response to a random read range corresponding to the random read operation meeting a preset condition, the memory controller may be configured to adjust capacity for storing different levels of mapping tables in the buffer.
