The storage device includes a semiconductor memory device and a device memory. The semiconductor memory device includes a plurality of non-volatile memory cells. The device memory stores validity information of host performance booster (HPB) sub-regions included in each of HPB regions cached in the host memory. The storage device determines to deactivate at least one HPB region among the HPB regions cached in the host memory based on the validity information included in the device memory, and transfers a message recommending to deactivate the determined HPB region to the host."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage device for improving read performance and method of operating the same","description":"A storage device communicates with a host including a host memory.
