    Abstract: Methods of fabricating semiconductor device are provided including forming first through third silicon crystalline layers on first through third surfaces of an active region; removing the first silicon crystalline layer to expose the first surface; forming a bit line stack on the exposed first surface; forming bit line sidewall spacers on both side surfaces of the bit line stack to be vertically aligned with portions of the second and third silicon crystalline layers of the active region; removing the second and third silicon crystalline layers disposed under the bit line sidewall spacers to expose the second and third surfaces of the active region; and forming storage contact plugs in contact with the second and third surfaces of the active region.

    Abstract: A method and an electronic device for network search. The network search method in an electronic device includes scanning a frequency band corresponding to a first communication system to search for a first Public Land Mobile Network (PLMN); when discovering a second PLMN as a result of the scanning, determining whether a frequency band of the second PLMN and a frequency band of a second communication system overlap each other; and when the frequency band of the second PLMN and the frequency band of the second communication system overlap each other, scanning the other frequency band excluding the overlapping frequency band in the entire frequency band corresponding to the second communication system to search for the first PLMN.
