PURPOSE: A data recording method and data recording device for improving operation reliability of an NAND flash memory are provided to improve the reliability of an operation by scrambling data which is recorded in the direction of a word line. CONSTITUTION: In a data recording method and data recording device for improving operation reliability of an NAND flash memory, the address of a memory cell is calculated(S62). The information of the memory cell corresponding to the memory cell address is extracted(S63). A data scramble mode is selected(S64). The data is scrambled(S65). The scrambled data is recorded in the memory cell(S66).

PURPOSE: A method and device for providing a SNS widget are provided to easily approach to the useful information by providing a widget which integrally manages SNS. CONSTITUTION: A display unit(113) displays a SNS(Social Network Service) Widget. A communication unit(111) receives SNS service information from external SNS servers(121-12n). A controller(112) incorporates the SNS service information into the widget. The controller receives SNS service information from an external SNS server which a user selects. The controller provides an update button about the SNS service information to Widget. If the update button is selected, the controller newly receives the SNS service information from the external SNS server.
Abstract:
A method for forming a penetration electrode, a MEMS structure using the same, and a manufacturing method using the same are provided to overcome limitation of a post process by forming the penetration electrode with a substrate material instead of a metal material. A substrate(110) is prepared. A penetration hole having a closed curved surface is formed at the substrate. A penetration electrode(120) is formed at the inside of the closed curved surface. The penetration electrode is formed with the same material as the material of the substrate. The penetration hole is filled with an insulator(114). The penetration electrode is used for transferring an electrical signal. The closed curved surface is formed with a ring-shaped structure. A conductive layer is formed by coating a conductive material between an outer surface of the penetration electrode and the insulator.
Abstract:
A character input device in a portable terminal and a method thereof are provided to output characters inputted from the terminal and peripheral characters adjacent to the inputted characters, and to modify the inputted characters by using direction keys, thereby realizing modification convenience when the characters need to be modified. An input unit(210) has plural character key buttons and direction keys. When characters are inputted through the input unit, a controller(230) confirms peripheral characters of the inputted characters, and controls so that an input key notify window which displays the inputted characters and the peripheral characters is outputted. A display(250) outputs the input key notify window under control of the controller.
Abstract:
An instant service method for DRR(Deficit Round Robin) data packet scheduling is provided to minimize transmission delay of data packets by servicing a data packet nearly at the activation time of a newly activated flow. A main control part services the first flow by forwarding a data packet corresponding to the first flow, activated at present, to a discharge part through an active list processing part according to scheduling(S302). If a new flow, as a new data packet is inputted from the external, is activated in the middle of serving the first flow, the main control part inserts the new flow into link list information, stored in a specific area of a packet memory, as a flow of the next order(S304,S306). Then, the main control part stores information on the new flow in a flow information storage part. If service of the first flow is completed(S308), the main control part controls the active list processing part so that the new service flow can be serviced in the next order(S310). If service of the new flow is completed, the main control part confirms the next flow pointer among information of the new flow and controls the active list processing part so that the second service flow can be serviced(S312).
Abstract:
A driving apparatus of a BLDC(BrushLess DC) motor is provided to prevent an overheat of the motor without stopping the motor by repeatedly reducing an output thereof with a certain ratio in case of the temperature to rise consecutively. In a driving apparatus of a BLDC motor, a motor includes a rotor and a stator. A power module supplies a power to the motor. A temperature sensor detects a temperature of the motor and the power module. A storing unit(30) stores the temperature of the temperature sensor. A control unit(16) compares the temperature detected by the temperature sensor with a reference value, calculates a temperature variation ratio within a certain time by using the temperature stored at the storing unit(30) and controls an output of the motor by using the same in a case of the motor to be determined as the overheated.

PURPOSE: A built-in antenna device of a handheld wireless terminal is provided to minimize electronic wave of the antenna device that is penetrating into a human body. CONSTITUTION: A built-in antenna device of a handheld wireless terminal comprises a main body formed by a top casing frame(112) and a bottom casing frame(111), a RF board(20) mounted inside the main body, and a shield cover(21) mounted on the RF board(20) for shielding electronic wave from electronic components on the RF board(20). A plate type antenna(10) made of metal material is mounted on the rear side of the RF board(20) so as to be kept away from a human body as far as possible. The plate type antenna(10) has bent pieces(11,12) electrically connected to the RF board(20) by soldering. The plate type antenna(10) has grooves(13,14) and protrusions(15,16) to operate in an available frequency band.
