    • Provided is a semiconductor memory device including a sub-word-line driving circuit capable of reducing an amount of leakage current due to coupling. The semiconductor memory device includes a word-line enable signal generating circuit and a sub-word-line driving circuit. The sub-word-line driving circuit provides a pull-down current path between a selected word line and ground for a pulse type period of time in a precharge mode following an active mode for the selected word line, generates a word line driving signal on the basis of a main word line driving signal, a first sub-word-line control signal, and a second sub-word-line control signal, and provides the word line driving signal to a memory cell array. The semiconductor memory device may reduce an amount of leakage current flowing to a ground through the sub-word-line driving circuit.

    • There is provided a method of processing an ultrasound spectrum image. According to such method, a spectrum image is formed based on ultrasound data and then the noise is removed from the spectrum image. The noise-removed spectrum image is matched with one or more spectrum models representing specific spectrum types. Then, whether or not the noise-removed spectrum image contains an aliasing is checked. If the noise-removed spectrum image contains the aliasing, then the aliasing is removed from the noise-removed spectrum image to provide a noise-removed spectrum image without the aliasing. Thereafter, contour tracing is performed on the noise-removed spectrum image without the aliasing to detect contour points. Further, peak tracing is performed on the noise-removed spectrum image without the aliasing to detect peaks.
    • 提供了一种处理超声波频谱图像的方法。 根据这种方法,基于超声数据形成频谱图像,然后从频谱图像中去除噪声。 噪声消除的光谱图像与表示特定光谱类型的一个或多个光谱模型相匹配。 然后,检查噪声去除的频谱图像是否包含混叠。 如果噪声去除的频谱图像包含混叠,则从去除噪声的频谱图像中去除混叠,以提供没有混叠的噪声去除的频谱图像。 此后,对噪声去除的频谱图像执行轮廓跟踪,而不需要混叠来检测轮廓点。 此外,在没有混叠的噪声去除的频谱图像上执行峰值跟踪以检测峰值。
