Abstract: A storage system may include: a host device including a host memory and configured to: set a size of a host memory buffer (HMB) based on an HMB ID indicating the size of the HMB; and allocate a portion of the host memory as the HMB, the portion corresponding to the size of the HMB. The storage system may further include a storage device including a non-volatile memory and configured to: generate the HMB ID indicating the size of the HMB, which is based on capacity of the non-volatile memory and communication speed between the host device and the storage device; and transmit the HMB ID to the host device.

Abstract: An operating method of a storage controller includes, storing data and a source type of the data in a cache memory, when a cache hit occurs, determining a source type of data corresponding to the cache hit and updating a hit count corresponding to the determined source type among a plurality of hit counts, determining a source type with a dominant hit rate among a plurality of source types based on the plurality of hit counts, operating in a first mode when a result of the determining indicates that the source type with the dominant hit rate is a first type, and operating in a second mode when the result of the determining indicates that the source type with the dominant hit rate is a second type.
