  • Patent number: 11494307
    Abstract: A computing system includes a host and a storage device. The host includes a host memory, and the storage device includes a processor, a semiconductor memory device and a device memory which caches mapping information of the semiconductor memory device. In operation, the processor transmits to the host read data and mapping table entry information of a logical address region corresponding to the read data in response to a read request. The mapping table entry information is transmitted to the host based on features of the logical address region. Additionally, the host may transmit a read buffer request corresponding to the mapping table entry information to the storage device, and the storage device may transmit mapping information corresponding to the read buffer request to the host, which then stores the mapping information in the host memory.
