Abstract
A mobile System on Chip (SoC) comprises a microprocessor and a first memory controller configured to control a refresh of a first memory. A temperature sensor detects a temperature in the first memory. When first temperature information received from the temperature sensor indicates that the detected temperature deviates from a predetermined temperature range, the first memory controller controls the first memory so as not to perform a self refresh. When second temperature information received from the temperature sensor indicates that the detected temperature is in the predetermined temperature range, the first memory controller outputs a self refresh command to the first memory.
