Abstract:
Disclosed herein is a method for displaying an expanded advertisement in which advertisement data including an optimized value is displayed when user's interaction satisfies the optimized value. The method for displaying the expanded advertisement comprises displaying advertisement data when detecting that an user accesses a service page, determining existence of an user's interaction of the client with respect to the displayed advertisement on the service page, verifying whether the interaction of the client satisfies a predetermined advertisement displaying basis when the interaction of the client exists, and displaying the expanded advertisement data when the interaction of the client satisfies the advertising displaying basis.
Abstract:
A peripheral voltage generator is provided for reducing an operating current by generating a peripheral voltage within a mobile SDRAM, and a current is used in a deep-power down mode and a self refresh mode to thereby enhance operational characteristics. The peripheral voltage generator includes a reference voltage generating unit for generating a peripheral reference voltage having a different level in response to an enable signal and a self-refresh signal; a comparing unit for comparing the peripheral reference voltage with a peripheral driving voltage to thereby output a peripheral voltage control signal based on the comparison result; and a peripheral voltage control unit for generating the peripheral driving voltage having a first peripheral level in response to the peripheral voltage control signal.
Abstract:
Disclosed is a slurry and method for chemical-mechanical polishing operation. The slurry may contain abrasive particles, an oxidizer, a pH controller, a chelating agent and water. The viscosity of the slurry may be in the range of about 1.0 cP—about 1.05 cP, so that the step difference may be reduced between regions with patterns and without patterns even after completing the chemical-mechanical polishing operation. A permissible rate of depth of focus (DOF) may not need to be controlled in the subsequent photolithography operation, which may enable the subsequent photolithography operation to be conducted by an optical system with relatively low DOF.
Abstract:
Disclosed is an apparatus for controlling a self-refresh period in a memory device capable of normally performing a self-refresh operation that is indispensable to the operation of a volatile memory device using a refresh period control even if the inner temperature of the memory device is changed. The apparatus determines different bank refresh periods according to the self-refresh entering time in a self-refresh mode, and thus the refresh operation can properly be performed to cope with the change of inner temperature of the memory device.

A voltage generator for a peripheral circuit, the voltage generator includes: a voltage supplier supplying a peripheral circuit voltage having a voltage level maintained at a reference voltage level, the peripheral circuit voltage outputted in response to a driving signal; and a voltage level compensator increasing the voltage level of the peripheral circuit voltage in response to a column path command.
Abstract:
An molding apparatus includes a core having a recessed part corresponding to a protruding part of a molded article, an ejector pin movably provided in the core to eject the molded article, an ejector sleeve movably provided in the core to push the protruding part of the molded article, and an ejector actuating part to move the ejector pin and the ejector sleeve together to a separation position where the protruding part of the molded article is separated from the recessed portion of the core, to bring the ejector sleeve into a stop position so that the ejector sleeve does not protrude from the core, and to move the ejector pin from the separation position to a removal position where the molded article is spaced apart from the core by a predetermined distance. Accordingly, the molding apparatus is capable of preventing damage caused on an ejector sleeve.
Abstract:
There is provided a bitline driving circuit and its driving method for minimizing a leakage current flowing between a wordline and a bitline in a power down mode and a self-refresh mode. The bitline driving circuit for reducing a leakage current in a semiconductor memory device includes a main driving block for precharging a bitline pair connected to a sense amplifier with a same voltage level, controlled by a main bitline equalizing signal; a sub driving block for equalizing a voltage level of a bitline pair connected to a cell array voltage in a precharge mode, controlled by a sub bitline equalizing signal; and a bitline isolation block for electrically disconnecting the main driving block and the sub driving block, controlled by a bitline isolation signal.
Abstract:
Chemical mechanical apparatuses including a polishing pad conditioning unit for improving a conditioning rate and wear uniformity of a polishing pad are provided. In one aspect, a chemical mechanical polishing apparatus includes a polishing pad conditioner including conditioning disks disposed in a radial direction of a planarizing surface of a circular polishing pad and contacted with the planarizing surface of the circular polishing pad during rotation of the circular polishing pad. The conditioning disks are connected to first drive units supported by an arm disposed over the circular polishing pad and extended in a radial direction of a planarizing surface of the circular polishing pad. The arm is connected to second drive units. The second drive units move the arm horizontally and reciprocally in the radial direction of the planarizing surface of the circular polishing pad. Thus, a conditioning rate and wear uniformity of the polishing pad may be improved.
Abstract:
A mobile communication system and method for providing a broadcast service to at least one access terminal connected to a broadcast server providing the broadcast service. In the system and method, an access network changes a physical channel allocated to a plurality of broadcast channels at least once, provides the broadcast service to the access terminal using the changed physical channel, and transmits change information of the physical channel to an access terminal that transmitted a predetermined registration message if the registration message is received from the access terminal. The access terminal transmits the registration message to the access network, receives the change information of the physical channel in response, and receives data of a desired broadcast channel through the changed physical channel.
Abstract:
The present invention relates to a dermal substitute comprising the biodegradable polymer such as collagen and the biomaterial such as amnion, the preparation method and the use thereof. Specifically, the present invention provides with an amnion-collagen sponge complex structure prepared by attaching, inserting or incorporating an amnion obtained from placenta to/in collagen. Inventive dermal substitute can be applied to surgery and wound requiring skin graft, for example, severe burns such as second-degree burn, without rejection by immune system. Further, inventive dermal substitute with amnion instead of silicone membrane has several advantages, such as better biocompatibility, anti-inflammatory activity and promoting activity of wound healing and commercial utilization as basement membrane. Also, inventive complex structure can be used as the basic matrix of bio-artificial skin for culturing cells and the biodegradable basic matrix for preparing artificial organs.
