Claim 14:
15. A memory system comprising:
at least one host memory including a plurality of HPB (high performance boosting) entry storage regions, the plurality of HPB entry storage regions including at least a first HPB entry storage region and a second HPB entry storage region, the at least one host memory configured to store at least one HPB entry in at least one HPB entry storage region of the plurality of HPB entry storage regions;
at least one host controller configured to output a read command including the at least one HPB entry;
a plurality of storage units configured to store user data; and
at least one device controller configured to receive the read command from the at least one host controller, the read command including HPB entry type information, the HPB entry type information indicating a type of the HPB entry, wherein
the plurality of HPB entry storage regions includes at least a first HPB entry type storage region corresponding to a first HPB entry type and a second HPB entry type storage region corresponding to a second HPB entry type,
the first HPB entry type storage region is configured to store mapping information between a logical address associated with the read command and a physical address associated with the read command, and indexing information indicating a location of the second HPB type entry storage region associated with the read command,
the second HPB type entry storage region is configured to store additional information associated with a read operation performed in response to the read command,
the read command further including at least one of the mapping information and the indexing information associated with the read command from the first HPB entry type storage region, and the additional information associated with the read command from the second HPB entry type storage region, and
the at least one device controller further configured to read data stored in the plurality of storage units based on at least one of the mapping information, indexing information, and the additional information in response to the read command.
