Abstract: 전기적인 리라이트기능을 구비한 불휘발성 반도체기억장치에 관한 것으로써, 저소비전력이고, 고속으로 동작하며, 실효적인 셀면적을 저감하고, 또한 10 5 회 이상의 리라이트회수를 보증하여 라이트, 디스터브특성 모두 최적하게 하기 위해, 불휘발성 반도체기억장치의 메모리셀은 부유게이트전극(3)을 갖는 MOSFET만으로 이루어지는 1트랜지스터형의 메모리셀로써, 라이트동작을 실행할때에는 n형 드레인영역(7)에 정전압을 인가하고, 제어게이트(5)에 부전압을 인가하고, 소오스영역(6)을 접지하고, 소거동작을 실행할때에는 제어게이트(5)에 정전압을 인가하고, 다른 모든 전극과 반도체기판(1)을 접지하고, 터널현상을 이용해서 라이트, 소거의 양 동작을 실행하므로 저소비전력을 달성 할 수 있으며, 특히 워드선에 부전압을 이용하고 있으므로 데이타라이트시의 트레인전압을 낮게할 수 있고, 그 결과 채널부의 게이트산화막의 저하가 경감된다.

Title: Magnetic bearing system with a load-meter
Inventor: LEE JONG-WON

Abstract: In a magnetic bearing system, one or two load-meters(4) adhere directly between a radius-oriented bearing stator core(2) and a sensor support pedestal(18). The radius-oriented bearing stator core(2) isn't in contact with a base(6), and the sensor support pedestal(18) is attached on the base(6), so that an electromagnetic force working for radius-oriented and axial bearing is directly applied to the load-meter(4).
