    摘要： A multiplexer for a semiconductor memory device which has at least two pads for inputting data signals from the outside. The multiplexer has at least two input lines for inputting the data signals from the at least two pads, respectively, at least two control lines for inputting control signals for switching the data signals from the at least two input lines, respectively, and at least two switching circuits, each of the at least two switching circuits transferring the data signal from a corresponding one of the at least two input lines to an output line in response to the control signal from a corresponding one of the at least two control lines and having a floating node formed to be electrically isolable from the output line and the corresponding input line to prevent a loss of the data signal on the output line. According to the present invention, the multiplexer can prevent a data loss due to a disturbance and accurately transfer the data signals from the at least two pads.

    摘要： The present invention relates to computing circuits and method for running an MPEG-2 AAC or MPEG-4 AAC algorithm efficiently, which is used as an audio compression algorithm in multi-channel high-quality audio systems, on programmable processors. In accordance with the present invention, the IMDCT process which takes large part of the amount of the operations in implementation of an MPEG-2/4 AAC algorithm can be performed in efficient. In addition, while the architecture of the existing digital signal processor is still used, the performance can be improved by means of the addition of the architecture of the address generator, Huffman decoder, and bit processing architecture. After all, to design and change the programmable processor is facilitated.

    摘要： An integrated circuit includes a data bus and a first memory device coupled to the data bus. The first memory device is configured to provide a first signal in response to completing a power-up sequence of the first memory device. The integrated circuit includes a second memory device coupled to the data bus. The second memory device is configured to provide a second signal in response to completing a power-up sequence of the second memory device. The integrated circuit includes a controller configured to access the first memory device and the second memory device based on the first signal and the second signal.
