    摘要: In a sense amplifier circuit, an output potential is set in a data output state when an operation of the sense amplifier is a worst pass before the start of read access. In a memory read mode, when data corresponding to the worst-pass operation of the sense amplifier circuit is read out, the circuit is previously set in a corresponding data output state. A time delay (gate delay) by a gate does not occur. In contrast, when data corresponding to the best-pass operation of the sense amplifier circuit is read out, the gate delay occurs by this operation. The gate delay, however, is shorter than that of the worst pass. As a result, only the best pass is present as the operation mode of the sense amplifier circuit. Therefore, a high operation speed is achieved, so that a high read speed of the entire memory is achieved.

    摘要: This invention is a D/A converter including a preset current source, first and second differential switches for selectively deriving an output current of the preset current source in response to complementary signals supplied to control electrodes thereof, and an imaginary short circuit for connecting output portions of current paths of the switches to each other. Variation in the voltage at the time of switching operation of the differential switch can be suppressed by use of the imaginary short circuit with the above construction, thus making it possible to enhance the operation speed.

    摘要: A drive circuit for driving a display panel having wirings and display devices to be connected to the wirings, has a first switch that transits potential of the wirings toward the first potential, a feedback amplifier that maintains the potentials of the wirings at the first potential, and a second switch that selects whether or not to supply an output from the feedback amplifier to the wirings. The first switch and the second switch are connected to the wirings in parallel. A drive performance of the first switch is lower than that of the feedback amplifier. As a result, stable driving waveforms can be output in a simple and inexpensive circuit configuration.

Either of the source and the drain of the second MOS transistor is connected to the gate of the first transistor. The other is connected to the output terminal. The circuit further includes a device for supplying a bias voltage to a gate of the second transistor so that the first and second transistors remain turned off at different gate bias potentials and the second transistor turns on before the first transistor when the output signal is raised to the predetermined potential level to keep the first transistor remaining turned off. The circuit further includes a device for restricting current flow from the output terminal to the predetermined potential side through the first and second transistors.
