An electronic device is provided that includes a housing including a key hole and a vent hole, a button member including a body part disposed to cover the key hole and the vent hole, and a button protrusion inserted into the key hole, a substrate member including a switch actuated based on the button protrusion, a base disposed between the housing and the substrate member to cover the substrate member, a waterproof member including a sealing part, formed to protrude from the base to surround a perimeter at least one of the key hole and the vent hole, which has at least a part in close contact with the outer wall, a conduit for connecting an internal space and outside of the electronic device through the vent hole, and a waterproof cover disposed on the conduit so as to block moisture flowing in through the vent hole.

Button device and electronic device comprising same

A semiconductor memory device includes: a memory core including memory cells and configured to output core data stored in the memory cells in response to a read request, a command decoder configured to decode at least one command input from an external device, a command log register configured to sequentially store the at least one command in response to a register enable signal and output the at least one command as a command log in response to a command log read signal, and a mode register set configured to generate the register enable signal or the command log read signal in response to a mode register set command transmitted to the command decoder.

Semiconductor memory device including command log register and command log output method thereof

An integrated circuit device, a semiconductor substrate, and a test system including the integrated circuit device are disclosed. The integrated circuit device includes a power terminal configured to receive a source voltage, a power via connected to the power terminal and passing through at least one of a number of layers, a number of inductive vias arranged apart from the power via and passing through at least one of the number of layers, a number of wirings connected to ends of at least some of the number of inductive vias and configured to form a coil wound in toroidal form together with the number of inductive vias, around the power via, and a test terminal configured to output an induced voltage in the coil externally of the integrated circuit device, in response to the supply of the source voltage.

Integrated circuit device, semiconductor substrate, and test system including the integrated circuit device

An electronic device according to one embodiment may include: a housing having a first side facing a first direction, a second side facing a second direction opposite to the first direction, and a side surrounding at least a portion of a space between the first side and the second side; a display disposed on the first side of the housing; a detachable input device disposed to surround the display on the first side; and a coupling structure that detachably couples the detachable input device to the housing. Other embodiments may be possible.

Electronic device including detachable input device

A charging apparatus and an electric vehicle including the same are disclosed. The charging apparatus includes a rectifier to rectify input alternating current (AC) power in a charging mode, an interleaved buck-boost converter to convert the rectified power into direct current (DC) power to supply the converted DC power to a battery, the interleaved buck-boost converter including a plurality of buck-boost converters, and a converter controller to control the interleaved buck-boost converter, wherein a first buck-boost converter of the interleaved buck-boost converter includes a first buck switching element connected to the rectifier, a first boost switching element, an inductor connected between the first buck switching element and the first boost switching element, a first diode connected in parallel between the first buck switching element and the inductor, and a second diode connected between the first boost switching element and an output of the interleaved buck-boost converter.

Charge apparatus and electric vehicle including the same

A method of providing channel state information feedback in a wireless communication system is provided. The method includes measuring original channel state information for each of a plurality of channels. An offset vector is applied to the original channel state information to generate modified channel state information. A subset of the channels is identified based on the modified channel state information. The original channel state information or the modified channel state information is reported.

Method and system for providing channel state information feedback in a wireless communication system

A system and method for inter-cell interference avoidance. A device capable of performing channel estimation is configured to divide a codebook into two sets. A first set of said two sets corresponds to codebook information that will cause an interference in a received signal to be less than a threshold. The device further is configured to send feedback information corresponding to the first or second set, or both. A base station is configured to select a preceding vector or matrix based, in part, on a portion of the feedback information.
