A semiconductor module includes a semiconductor package generating thermal energy, a heat collecting member transferring thermal energy from the semiconductor package to a heat collection area in the heat collecting member, a heat radiating member transferring thermal energy received from the heat collecting member and package to the outside, and a thermoelectric device transferring thermal energy through the heat collection area to the heat radiating member via the thermoelectric effect. The heat collecting member and heat radiating member may be otherwise insulated so thermal energy is transferred and controlled by the thermoelectric device. The package may be a dynamic random access memory (DRAM), microprocessor, central processing unit (CPU), graphic processing unit (GPU), or flash memory. The heat radiating member may be an external case of a solid state disk (SSD), and the thermoelectric device may be a Peltier cooler controlled through a power line.
