Claim 25:
26. A semiconductor device comprising:
a plurality of volatile memory devices, each comprising a plurality of volatile memory cells arranged in a plurality of rows; and
a memory controller configured to:
provide temperature information of one or more volatile memory devices among the plurality of volatile memory devices, but not all of the plurality of volatile memory devices, to a host device when the semiconductor device temperature is out of a first temperature range;
provide temperature information of each of the plurality of volatile memory devices in the semiconductor device to the host device when the temperature information of at least one of the one or more volatile memory devices is out of a second temperature range; and
receive 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 from the host device,

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.
