Abstract:
A data strobe signal noise prevention apparatus and semiconductor integrated circuit includes a transition protection unit configured to protect a transition of a data strobe signal in response to a control signal and a controller configured to determine when a burst operation completes and to generate the control signal.
Abstract:
A mobile communication apparatus is provided. The mobile communication apparatus includes an information receiver to receive, from a serving base station, target base station information corresponding to at least one target base station located in a neighboring cell, and a controller to examine the target base station information and to perform a handover to the at least one target base station based on whether the at least one target base station supports a multi-band, and whether the at least one target base station provides a broadcast service.
Abstract:
Provided is a multimedia broadcast and multicast service controlling apparatus and method based on a user location. The multimedia broadcast and multicast service controlling apparatus may receive MCCH information, may periodically update a service list of a mobile terminal based on the received MCCH information, the service list listing services that are providable, may register a service in a pending list when the service is not included in the updated service list and is requested to be provided, and may provide the service registered in the pending list when the mobile terminal reaches a location where the mobile terminal may provide the service registered in the pending list.
Abstract:
A semiconductor memory device includes a source signal generation unit configured to generate a source pulse signal having a pulse width which is determined depending on an interval between an input of an active signal and an input of a column command signal, which is inputted after an active command, and a column decoding unit configured to generate a column select signal in response to an address and the source pulse signal.
Abstract:
A dual-mode mobile communication terminal and a method, which automatically recognize a card and select a drive mode. The dual-mode mobile communication terminal includes a first slot and a second slot into which a first card or a second card having subscriber information for a first communication or a second communication are inserted, and a control unit for automatically selecting a drive mode according to a type of a card inserted into the first slot or the second slot.
Abstract:
The disclosed invention relates to a method of manufacture of transparent ceramics such as yttrium aluminum garnet by tape casting. The method entails forming a mixture of ceramic oxide, dispersant and organic solvent, milling the mixture to produce a first slurry, mixing the first slurry with an organic binder and a plasticizer to form a treated slurry, milling the treated slurry to produce milled slurry, tape casting the milled slurry to produce cast tape, drying the cast tape to produce dried tape, stacking portions of dried tape to form an assembly, compressing the assembly to produce a preform, heating the preform to produce a green preform, and sintering the green preform to produce transparent yttrium aluminum garnet. The method may be used to produce a unitary ceramic product having differing transparent sections as well as transparent ceramic product having a dopant gradient across a portion of the thickness of the product.
Abstract:
