Abstract:
Disclosed are a non-volatile memory device and a method of programing the same. The non-volatile memory device may include a memory cell array and a row control circuit. In the program operation mode of the non-volatile memory device, a program voltage signal (VPGM) is applied to a select word line after a predetermined time has elapsed from an apply time of a first pass voltage signal, and a second pass voltage signal is applied to a non-select word line adjacent to the select word line when the VPGM is applied to the select word line. The rising time period of the program voltage signal applied to the select word line may overlap with the rising time period of the second pass voltage signal applied to the non-select word line adjacent to the select word line. Thus, the parasitic capacitance between the select word line and the non-select word line adjacent to the select word line can be reduced and the program performance of the non-volatile memory device can be improved.
Abstract:
An AND-type and NOR-type flash memory arrays, a manufacturing method thereof and an operating method thereof are provided to form plural same silicon pins having certain width and height on an upper portion of a substrate. A local bit line(LBL1) is connected to bit lines(BL1,BL2,BLn) via a first select transistor(ST11). Memory cells(M11 to Mm1) are connected in parallel to the local bit line and the local source line. A local source line(LSL1) is commonly connected to a source of the respective memory cells, and a common source line(CSL) is connected to the local source line via a second select transistor(ST21). A drain select line(DSL) and a source select line(SSL) are electrically connected to a gate of the first select transistor and a gate of the second select transistor. Plural word lines(WL1 to WLm) are connected to a gate of each memory cell. The local bit line and the local source line have a first doped layer and a second doped layer which are vertically spaced apart from silicon pins.

화상형성장치의 정착장치가 개시된다. 개시된 화상형성장치의 정착장치는 실린더형의 정착롤러와, 상기 정착롤러와 대향되게 설치되어 그들 사이를 통과하는 용지를 상기 정착롤러로 밀착시키는 가압롤러와, 상기 정착롤러 및 가압롤러를 동시에 가열시키는 유도가열수단;을 구비하는 것을 특징으로 한다. 이에 따르면, 폐쇄형 자기 코아로 원통롤러 및 가열롤러의 중공부를 연결하여 원통롤러 뿐만 아니라 가압롤러도 함께 가열함으로써 정착장치가 정착온도에 도달되는 시간을 단축시킬 수 있다. 또한, 토너 정착시 가압롤러로 빼앗기는 열을 줄임으로써 정착열량이 증가되는 컬러 레이저 프린터, 고속 레이저 프린터 또는 대형 용지의 인쇄에 적용할 수 있다.
Abstract:
A fixing apparatus of an image forming apparatus is provided to reduce heat loss in the fixing apparatus by radiating heat formed at a core by induced heating to the inside of a pressure roller so as to heat the pressure roller. A pressure roller(113) is installed to face with cylinder type of a fixing roller(112) and thereby makes paper close to the pressure roller, where the paper passes between the pressure roller and the fixing roller. An induced heating part heats the fixing roller and the pressure roller at the same time. The induced heating part includes a core(117) that forms a closed magnetic circuit through a central hole part of the fixing roller and the pressure roller, a coil(114) spirally wrapping an external surface of the core and an alternating current voltage source for applying an alternating current voltage to both ends of the coil.
