    摘要: An electronic device disposed on a door frame includes a back plate attached to the door frame, a housing coupled to the back plate, a first antenna that transmits or receives a signal having a first wavelength with an external electronic device, a second antenna that is disposed closer to the back plate than the first antenna and that transmits or receives a signal having the first wavelength with the external electronic device, an electric-wave blocking member that is disposed between the back plate and the second antenna and that blocks a signal reflected by the door frame, and at least one processor operatively connected with the first antenna and the second antenna. The first antenna and the second antenna are disposed inside the housing, and an antenna pattern of the second antenna is different from an antenna pattern of the first antenna.

    摘要: Provided are an electronic device and an operation method thereof. The electronic device may include: first and second antennas to receive a signal output by an external electronic device; a communication circuit configured to control the first antenna and the second antenna; and a processor. The processor may be configured to: receive the signal through the first antenna and the second antenna; measure a first distance between the first antenna and the external electronic device using the signal received by the first antenna; measure a second distance between the second antenna and the external electronic device using the signal received by the second antenna; determine a movement direction of the external electronic device based on a change in a difference between the first distance and the second distance; and perform a preset operation corresponding to the movement direction of the external electronic device. Other embodiments are also possible.

    摘要: A hammer refresh row address detector includes a control logic unit that receives a row address applied along with an active command, to increase a hit count stored in a corresponding entry when the row address is present in candidate aggressor row addresses stored in n entries. The control logic determines a candidate aggressor row address stored in an entry in which the hit count equals a threshold value to be a target aggressor row address. The control logic generates a victim row address adjacent to the target aggressor row address as a hammer refresh row address to accompany a hammer refresh command. The control logic increases the miss count value when the row address is not present in the candidate aggressor row addresses stored in the n entries and no hit count within the n entries is identical to the miss count value.
