    • A column repair circuit for a semiconductor memory having an input/output selection circuit for inputting a control signal, selecting a bit line and a bit bar line corresponding to a faulty memory cell and replacing the selected bit line and bit bar line with a spare bit line and a spare bit bar line. The input/output selection circuit includes an input stage for inputting the control signal, a spare bit line and a spare bit bar line, and a plurality of fuses each having one side connected to the input stage and other side connected to a plurality of resistors. The other side of the resistors are connected to ground for outputting the output signals. The input/output selection circuit further has a plurality of n-channel MOSFETs each including a gate connected to each of the other stages of the plurality of fuses via the resistors in a 2 to 1 manner for inputting the output signals. The drains of the MOSFETS are connected to the spare bit line and spare bit bar line and their sources are connected to each of the plurality of data bit lines and the plurality of data bit bar lines for functioning as a switch. Therefore, the present invention can provide the column repair circuit for a semiconductor memory which is capable of increasing its repair yield by adding the input/output selecting circuit enabling input/output selecting.

    • A method for a terminal including a first media access control (MAC) layer and a second MAC layer to create an authorization key includes performing a first network entry process to a base station through the first MAC layer, and performing a second network entry process for a frequency overlay to the base station through the second MAC layer. In this instance, the first network entry process includes acquiring a key for generating an authorization key through an authentication process according to an authentication method negotiated with the base station, and generating a first authorization key through the key for generating the authorization key. The second network entry process includes generating a second authorization key by using the key generated in the first network entry process for generating the authorization key.

    • A proximity sensing method of a portable terminal and a proximity sensing apparatus thereof are provided. The proximity sensing method of a portable terminal with an illumination sensor includes determining an output of the illumination sensor, determining that the portable terminal is proximate to an object when the output of the illumination sensor has a set pattern, and determining that the portable terminal is not proximate to the object when the output of the illumination sensor does not the set pattern. The proximity sensing method of a portable terminal may support a proximity sensing function using an illumination sensor instead of a proximity sensor to reduce a manufacturing cost of the portable terminal. In addition, since the method does not need a separate proximity sensor, it may address a lack of mounting space problem.
