  • Publication number: 20100332925
    Abstract: A semiconductor memory apparatus according to the embodiment includes a test mode controller, a first data alignment unit, a decoder, a test executing unit and a second data alignment unit. The test mode controller is configured to generate test enable signals in response to a test mode setting signal and a read command. The first data alignment unit is configured to parallely align first input data that are input in series, generate first alignment data, and transmit it to the first data driver. The decoder is configured to decode the first alignment data in response to the test enable signal and generate the decoding signal. The test executing unit is configured to execute the preset test mode in response to the decoding signal. The second data alignment unit is configured to parallely align second input data, which are input in series, in response to the test enable signal, generate second alignment data, and transmit it to a second data driver.

  • Patent number: 7689425
    Abstract: A QoS call routing system using a counselor and a speech recognition engine comprises a speech recognition engine for recognizing speech and outputting characters and speech recognition results; a first counselor group terminal for reproducing the client's speech file to a counselor of a first counselor group so that the counselor may recognize the speech when the speech recognition result by the speech recognition engine is less than a reference value; a second counselor group terminal for allowing a counselor of a second counselor group to hear the client's speech so that the counselor may recognize the speech when the recognition by the counselor of the first counselor group has failed; and an IVR server for controlling the engine and terminals to provide information to the client.

  • Publication number: 20090070542
    Abstract: A method to divide a file or merge files using a file allocation table (FAT) in which the method to divide a file includes storing data of a first cluster, among data intended to be separated from the file, into a second cluster, and generating a first cluster chain and a second cluster chain using a file allocation table (FAT), the first cluster chain containing data remaining in the first cluster, and the second cluster containing data existing in the second cluster. As a result, time delay due to a file copy process and shortening of a lifespan of NAND flash are prevented, and a reserve capacity for editing purposes is minimized.
