A read latency corresponding to the read operation of the storage device is stored in a read latency table of the host device. A determination is made whether a latency change ratio exceeds a threshold value, based on the read latency stored in the read latency table. The data host requests a data retention operation from the storage device, through a retention command, when the latency change ratio exceeds the threshold value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Operating method for host device and memory system including host device and storage device","description":"A host device controls a storage device to perform a read operation of a read data unit with respect to selected memory areas.
