Abstract: A semiconductor package includes an interposer, an electronic device having a first side surface and a second side surface opposite to the first side surface, and including a plurality of memory dies stacked in a vertical direction, at least one first through pipe passing through the electronic device in the vertical direction adjacent to the first side surface, and moving a cooling liquid therein, and a plurality of thermal transmission lines extending in a horizontal direction inside the memory die, and extending in parallel from the first through pipe toward the second side surface.

Abstract: A twin engine improves fuel efficiency in a low-load section and generates sufficient output in a high-load section by selecting a specific bank or operating all of the banks in accordance with necessity of required load. The twin engine may include a plurality of engine banks that independently operates in a unit of a cylinder block equipped with a plurality of cylinders, transmissions that are provided at the same number of engine banks and disposed between output ends of engine banks, a power controller that selectively collects the power output from the output ends of transmissions and transmits the power to driving wheels, and a driving controller that controls the operations of the engine banks and the power controller, such that the engine banks are selectively or simultaneously operated in accordance with traveling conditions.
