    Abstract: An integrated circuit memory device and method including a direct mode assigns internal data and address signals to separate pins. In particular, a plurality of first pins is assigned to the plurality of internal data signals that provide the data to the memory array in direct test mode. A plurality of second pins is assigned to the plurality of internal address signals that provide the address to the memory array in direct test mode, wherein none of the pins included in first plurality of pins are included in the second plurality of pins.

    Abstract: A noise cancellation apparatus includes a noise estimation module for receiving a noise-containing input speech, and estimating a noise therefrom to output the estimated noise; a first Wiener filter module for receiving the input speech, and applying a first Wiener filter thereto to output a first estimation of clean speech; a database for storing data of a Gaussian mixture model for modeling clean speech; and an MMSE estimation module for receiving the first estimation of clean speech and the data of the Gaussian mixture model to output a second estimation of clean speech. The apparatus further includes a final clean speech estimation module for receiving the second estimation of clean speech from the MMSE estimation module and the estimated noise from the noise estimation module, and obtaining a final Wiener filter gain therefrom to output a final estimation of clean speech by applying the final Wiener filter gain.

    Abstract: Disclosed herein are an apparatus and method for preprocessing speech signals to perform speech recognition. The apparatus includes a voiced sound interval detection unit, a preprocessing method determination unit, and a clipping signal processing unit. The voiced sound interval detection unit detects a voiced sound interval including a voiced sound signal in a voice interval. The preprocessing method determination unit detects a clipping signal present in the voiced sound interval. The clipping signal processing unit extracts signal samples adjacent to the clipping signal, and performs interpolation on the clipping signal using the adjacent signal samples.

    Abstract: Disclosed is a conductive polymer, which is doped with an acid and has a weight-average molecular weight of 5,000 or less when provided in the form of a base type, with a solubility of 3% or more in a polar organic solvent. Because the conductive polymer is soluble in various polar organic solvents, the solvent may be freely selected depending on the end use of the conductive polymer and thus the conductive polymer has a very wide range of industrial applications. A method of preparing the conductive polymer is also provided, which is simple and generates a small amount of wastewater and thus reduces the preparation cost and is environmentally friendly.
