  • Publication number: 20220391093
    Abstract: Disclosed are a data processing system comprising: a memory system for providing a host with a memory map segment including map pieces; and the host for storing the memory map segment as a host map segment and converting a logical address into a physical address using the host map segment. The memory system stores changed map pieces in a map cache, inserts the changed map pieces in a response to a first command, and provides the host with the response. The host updates the host map segment based on the changed map pieces. When a read command includes a logical address and a physical address, the memory system accesses a memory device using the physical address of the read command according to whether the logical address of the read command is stored in the map cache.
