According to some embodiments of the invention, transistors of a semiconductor device have a channel region in a channel-portion hole. Methods include forming embodiments of the transistor having a channel-portion hole disposed in a semiconductor substrate. A channel-portion trench pad and a channel-portion layer are sequentially formed at a lower portion of the channel-portion hole. A word line insulating layer pattern and a word line pattern are sequentially stacked on the channel-portion layer and fill the channel-portion hole, disposed on the semiconductor substrate. The channel-portion layer is formed to contact the semiconductor substrate through a portion of sidewall of the channel-portion hole, and forms a channel region under the word line pattern. Punchthrough is prevented between electrode impurity regions corresponding to source and drain regions.

Provided is an apparatus and method for transmitting/receiving time information in a mobile communication system. In a method for calculating a current time in the mobile communication system, time information is received from a base station. Date information and parameters for calculation of time are obtained on the basis of the received time information. A lapse time length from a reference time is calculated on the basis of the parameters. A current time is calculated using the calculated lapse time length and the date information. The time information is periodically transmitted and received using the idle frame of an idle state and the stealing flag of a normal burst contained in a BCCH.
摘要:
An apparatus and a method for providing dual mode operation that stores two International Mobile System Identifier (IMSI) information in one SIM card is disclosed. The apparatus includes a controller and a SIM manager, wherein the recognizes mounting of one SIM card that stores two IMSI information, defines a first IMSI information corresponding to the SIM card as a master information, defines a second IMSI information as a second IMSI information, and transfers the second IMSI information to the SIM manager, wherein the SIM manager recognizes the second IMSI information as IMSI information of a SIM card not mounted, and recognizes that respective IMSI information has been separately stored as corresponding to having two SIM cards mounted.
摘要:
An operation method and apparatus of a mobile communication terminal supporting a dual mode are provided. The method includes determining if two Subscriber Identification Module (SIM) cards are inserted, searching for and registering with a cell of a first network supported by a first SIM card, and searching for and registering with a cell of a second network supported by a second SIM card during a non-paging duration of the first network.
