Claim 16:
17. An operating method of a host device, comprising:
receiving temperature information of one or more volatile memory devices among a plurality of volatile memory devices of a storage device, but not all of the plurality of volatile memory devices, when the storage device temperature is out of a first temperature range;
receiving temperature information of each of the plurality of volatile memory devices of the storage device when the temperature information of at least one of the one or more volatile memory devices is out of a second temperature range;
classifying the plurality of volatile memory devices into a plurality of groups based on the temperature information of each of the plurality of volatile memory devices; and
providing a setting command including a number of rows of the plurality of volatile memory devices to be refreshed differently based on the temperature information in a refresh operation of the plurality of volatile memory devices to the storage device,
wherein the setting command indicates the number of rows of the plurality of volatile memory devices to be refreshed differently for each of the plurality of groups based on the temperature information, and
wherein the plurality of volatile memory devices are classified into groups after the temperature information is obtained,
wherein the plurality of volatile memory devices comprises three or more volatile memory devices, and
wherein the one or more volatile memory devices includes two volatile memory devices corresponding to two pieces of temperature information having a largest difference among the temperature information of each of the plurality of volatile memory devices.
