  • Patent number: 7574638
    Abstract: The present invention provides semiconductor devices capable of being tested using one test pin and using an input/output pin without any test pins, and methods of testing the same. One semiconductor device comprises a test pin for inputting/outputting test data, an operation mode controller for activating an enable signal in response to an external reset signal and a clock signal, an operation mode storage for receiving serial data synchronized with the clock signal through the test pin in response to the enable signal, and an operation mode decoder for generating operation mode selection signals in response to the serial data stored in the operation mode storage.

  • Patent number: 6868118
    Abstract: A discrete multi-tone (DMT) processor receives predetermined control signals from a digital signal processor (DSP) within an asymmetric digital subscriber line (ADSL) modem, modulates transmission data in response to the control signals, and demodulates reception data. The DMT processor includes a frame synchronization signal generator, a transmitter, and a receiver. The frame synchronization generator generates a transmission frame synchronization signal and a reception frame synchronization signal in response to a cyclic prefix contained in the transmission data or reception data and a reception synchronization shift signal applied from the DSP. The transmitter DMT modulates and gain-controls the transmission data input in response to the transmission frame synchronization signal The receiver gain-controls and DMT demodulates the reception data response to the reception frame synchronization.

  • Patent number: 6864735
    Abstract: An apparatus and method for regenerating reset and clock signals and a high-speed digital system using the apparatus and method are provided. In the regenerating circuit of the invention, a clock circuit receives an external clock signal and generates there from an internal clock signal, which is forwarded to a plurality of clocked circuits such as, for example, D flip-flops. A reset circuit receives an external reset signal and generates therefrom an internal reset signal, which is forwarded to the clocked circuits to reset the clock circuits. A clock masking circuit masks the internal clock signal for a masking period such that the clocked circuits are not clocked during the masking period. The high-speed digital system of the invention includes a plurality of function blocks coupled on a bus. The reset and clock regenerating circuit of the invention generates internal reset and clock signals from externally applied reset and clock signals.

  • Patent number: 5913229
    Abstract: A buffer memory controller allows to sequentially store sampled data having variable bit length. That is, rather than assigning each sampled data to a single word of the memory, the sampled data is sequentially stored head to tail so that memory space is not wasted.
