Abstract:
PURPOSE: A complex programmable logic device code download method in a dual processor and a method thereof are provided to store a CPLD binary in a S/W binary data area in the dual processor, thereby automatically updating a CPLD code by CPLD binary update. CONSTITUTION: A host processor extracts a CPLD code from a CPLD(Complex Programmable Logic Device) binary in a S/W binary data area(307). A slave processor temporarily stores the CPLD code(311). The slave processor generates a JTAG(Joint Test Action Group) signal(315). The slave processor temporarily stores a CPLD code of the CPLD(321). The slave processor calculates a checksum value(325). The host processor displays a CPLD download complete message(329).
Abstract:
A semiconductor device and a formation method thereof are provided to form a share contact plug of a dumbbell shape, thereby reducing damage of a spacer disposed in a side of a gate electrode in a share contact hole forming process. A gate insulating layer(120) and a gate electrode(130) are formed on a semiconductor substrate(100). A spacer(140) is formed in a side wall of the gate electrode. An interlayer insulating film(150) is formed on the front of the semiconductor substrate. A shared contact hole including a first part(180a) exposing the gate electrode by pattering the interlayer insulating film, a second part(180b) exposing the semiconductor substrate and a third part(180c) connecting the first part and the second part is formed. The first part, the second part and the third part are arranged along a first direction. The first and second parts respectively have maximum widths in a second direction orthogonal to the first direction. The third part has a width smaller than the maximum widths of the first and second parts in the second direction.

Abstract:
A method and an apparatus for CABAC(Context-based Adaptive Binary Arithmetic Coding) encoding, a method and an apparatus for CABAC decoding, and a computer-readable recording medium storing programs for performing the methods are provided to restore original input data without an ambiguity occurrence by previously performing test decoding during an encoding process so as to prevent the occurrence of the ambiguity. The first context model based on statistics of previously input symbols and the second context model having a different MPS(Most Probable Symbol) value from the first context model are selected(S110). If a value of a current input symbol is equal to the MPS value of the first context model, or the second context model is not selected, the current input symbol is encoded using the first context model(S140). If the value of the current input symbol is different from the MPS value of the first context model, or the second context model is selected, the current input symbol is encoded using the second context model(S130).
Abstract:
A semiconductor memory device and its manufacturing method are provided to prevent short of an upper wire and a lower wire and to increase electrical characteristics of the semiconductor memory device. Lower wires(22) are formed on a semiconductor substrate(10) in one direction. An interlayer dielectric(24) is formed on the semiconductor substrate where the lower wires are formed. The interlayer dielectric is selectively etched to form a via hole(26) exposing the lower wires. A trench(28) is located in the interlayer dielectric by being arranged vertically with respect to the lower wires. The trench is projected from the lower wires toward one side. A lower portion of the projected region is connected to the via hole. The conductive layer for gap-filling the via hole and the trench is formed and planarized to form an upper damascene wire(46) within the interlayer dielectric.
