Title: Sense amplifier for memory array
Inventor: KEVIN ZANG
IPC: G11C11/419
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a sense amplifier for memory array without requiring a reference voltage circuit high in performance and simple in configuration. SOLUTION: FETs different are channel width are used for two pull-up paths or pull-down paths respectively. For example, when voltage at node 108 is equal approximately to voltage st node 120 at the time of turning on a FET 124, pull-up is caused at the node 108 and pull-down is caused at the node 120, the node 108 is stabilized in a high state and the node 120 is stabilized in a bias state, by making channel width of a first pull-up FET 104 larger than that of a second pull-up FET 114 or making channel width of a second pull- down FET 116 larger than that of a first pull-down FET 106. On the other hand, when voltage of the node 108 is lower than that of the node 120 by some threshold value or more, the node 108 is made low and the node 120 is made high while resisting the bias state, and they are stabilized.

Filed: 1989-11-30
Abstract: PURPOSE:To improve reproductivity of half tone by detecting surface potential of the photosensitive body by exposing the photosensitive body with half tone reproduction energy of a multiple number of grades, comparing this with E-V characteristic, and detecting and compensating the variation in the sensitivity of the photosensitive body. CONSTITUTION:The surface potential of the photosensitive body 1 exposed by a first half tone reproduction energy, consisting of multiple number of grades of half tone reproduction energy, is detected 12. Because compensation is carried out mainly with an average value of the deviation with the E-V characteristic, either photosensitive body electrifying voltage related to the image density or light beam outputting energy is compensated and controlled at a first feedback. After compensating and controlling, the surface potential is detected 12 by exposing the photosensitive body 1 with second half tone reproduction energy, and if there is any deviation with the E-V characteristic, either one of the photosensitive body electrifying voltage related to the image density, the light beam outputting energy, or developing bias which was not compensated and controlled at the first feedback is further compensated and controlled at second feedback as an auxiliary compensation. Thus, a stable half tone reproduction can be carried out well.
