Abstract:
A memory device includes an interface unit and a memory unit. The interface unit receives a clock signal, a command signal and a data signal, internally adjusts input impedance based upon at least one of the command signal and the clock signal, and generates internal control signal of the memory device based upon the command signal and data signal. The memory unit performs read/write operations based upon the internal control signal.

Abstract:
Disclosed are a laser processing apparatus and method that can effectively remove a low-k material formed on a wafer. A laser processing apparatus of the invention is a laser processing apparatus that processes a subject on which a low-k material is formed. The laser processing apparatus includes a laser generating unit that emits a laser beam; and an optical system that splits the laser beam emitted from the laser generating unit into two and irradiates the split laser beams onto the subject In this case, the optical system includes a pair of condensing lenses in which cut surfaces that are cut at a predetermined distance from central axes to be parallel to the central axes contact with each other, and the interval between the two split laser beams is the same as the interval between two edges of the low-k material in a removal subject region. According to the invention, after splitting a laser beam into two laser beams and primarily removing the edges of the low-k material in the removal subject region using the laser beams, the remaining low-k material between the edges is removed. As a result, it is possible to improve processing quality.
Abstract:
A method of multi-processing an object using a polygon mirror according to an embodiment of the invention includes setting processing parameters for individual layers of an object having a multilayer structure, performing laser processing on exposed layers in a region to be processed of the object according to the processing parameters using a polygon mirror, determining whether or not all of the layers of the object having a multilayer structure are processed, and if it is determined in the determining that not all of the layers are processed, progressing the performing of laser processing. Therefore, efficiency in processing the object can be increased, and cracks that occur in the object during laser processing using a polygon mirror can be minimized.

Abstract:
A non-volatile memory device having a hidden cell located separate from data storage cells, and a method of effectively managing an erase count of the non-volatile memory device. The method includes preparing the non-volatile memory device that includes a hidden cell located separate from data storage cells and is not accessible to users of the data storage cells, and increasing an erase count stored in an erase count storing region of the hidden cell corresponding to at least one erased data storage cell when the at least one data storage cell is erased.
Abstract:
An apparatus and method for providing a multicast/broadcast service in a mobile communication system. Upon detecting an occurrence of a multicast data packet, an Internet Protocol (IP) terminal converts the multicast data packet into an alternative multicast data packet, and transmits the alternative multicast data packet to a femto Node B. Upon detecting an occurrence of a broadcast data packet, the IP terminal converts the broadcast data packet into an alternative broadcast data packet, and transmits the alternative broadcast data packet to the femto Node B.
