Mobile system on chip (SoC) and mobile terminal using the mobile SoC, and method for refreshing a memory in the mobile SoC

A mobile SoC, comprising:

• a first memory controller configured to control a refresh of a first memory;
• and
• a second memory controller configured to an operation of a second memory,
• wherein a temperature sensor detects a temperature in the first memory, and when temperature information received from a temperature sensor indicates that the detected temperature deviates from a predetermined temperature range, the first memory controller reads at least a part of data stored in the first memory and outputs the read data to the second memory controller, and the second memory controller controls the output data so as to be stored in the second memory.

A mobile SoC, comprising:

• a microprocessor;
• and
• a first memory controller configured to control a refresh of a first memory,
• wherein if the first temperature information received indicates that the detected temperature deviates from the predetermined temperature range, the first memory controller outputs a first control signal to the microprocessor, and in response to the first control signal, the microprocessor changes a frequency of a clock signal generated by the microprocessor.
