Claim Text:
1. A device comprising: a first semiconductor chip; a second semiconductor chip stacked on the first semiconductor chip, the second semiconductor chip including a first plurality of through electrodes penetrating therethrough; and a refresh control unit which controls a cycle of a refresh for the second semiconductor chip in response to a first temperature signal received via at least one through electrode of the first plurality of through electrodes; wherein the first semiconductor chip includes a first temperature sensor outputting the first temperature signal, and the first temperature signal takes a first value when a temperature of the first semiconductor chip is equal to or higher than a first temperature and a second value when the temperature of the first semiconductor chip is lower than the first temperature, and wherein the refresh control unit controls the cycle to a first cycle when the first temperature signal takes the first value and to a second cycle that is greater than the first cycle when the first temperature signal takes the second value.
