Abstract:
PURPOSE: A semiconductor device for safe at EOS(Electrical Over Stress) is provided to protect a metal line and internal circuits from EOS surge by improving tolerance for EOS due to surge, over-current, and over-voltage. CONSTITUTION: A semiconductor device has ESD(Electro-Static Discharge) protection diodes(176,178) connected between a data input/output pad(170,180) and supply voltage and between the data input/output pad(170,180) and ground power in order to protect the data input/output pads(170,180) and internal circuits from ESD. An error of a semiconductor device due to undesired EOS surge is prevented by widening a metal line connected to the data input/output pads(170,180). The width of the metal line is widened as much as 20 or more micro meters. Accordingly, the metal line connected to the ESD protection diodes(176,178) is protected from the EOS surge.

PURPOSE: A network connecting method of a portable terminal and apparatus are provided to form a wireless channel corresponding to a release version which is able to provide support between the portable terminal and a network. CONSTITUTION: A control unit(140) creates connecting request information including an RRC(Radio Resource Control) unit in a release version which is able to support a user terminal(100). The control unit transmits the RRC connecting request message to a network. The control unit, based on the control of a message transmission unit(110), transmits the RRC connection request message. The control unit compares a release version of the RRC connecting establishment message with the release version of the RRC connecting request message.
Abstract:
PURPOSE: A service providing method and an apparatus thereof in a multiple RAT terminal are provided to improve the satisfaction of a service by confirming offer not right of the requested service. CONSTITUTION: A first communications unit(210) transmits and receives first communications signals among multiple RATs with one RAT(Radio Access Technology) from a first communications network. A second communications unit(220) transmits and receives second communications signals among the multiple RAT with RAT of the other one from the second communications network. In case the connected network is not the network offering the requested service, the controller performs the network change over through the second communications unit.
