Abstract: The present disclosure relates to an electronic device, and more specifically, to an electronic device including a printed circuit board including a heat-generating element arranged on one surface thereof, and a heat transfer coin provided such that one surface of the heat transfer coin comes into contact with a portion of the other surface of the printed circuit board, opposite to the heat-generating element, so as to dissipate heat generated from the heat-generating element. Accordingly, the present disclosure provides an advantage of improving heat dissipation performance without increasing the thickness of the printed circuit board.

Abstract: A communication apparatus is provided to include an apparatus enclosure that includes a substrate seating surface and at least one or more connection grooves formed on the substrate seating surface, a first printed circuit board disposed on the substrate seating surface, a second printed circuit board disposed on the substrate seating surface on one side of the first printed circuit board, and at least one or more connectors disposed within the connection groove and configured to electrically connect the first printed circuit board and the second printed circuit board.

Abstract: Provided herein may be a memory controller and a method of operating the same. The memory controller may include a SPO detector configured to output a detection signal when a SPO is detected, a memory buffer configured to store host data, and a power loss controller configured to, based on the detection signal, receive dump data corresponding to the host data, store the dump data and a dump age corresponding to the dump data, and output the dump data and the dump age to a memory device, wherein the dump age indicates a number of times that different items of host data have been dumped from the memory buffer to the power loss controller, and the power loss controller is configured to control a recovery operation corresponding to the SPO based on the dump age being received from the memory device.
