  • Patent number: 7339841
    Abstract: A method of testing internal signals of a memory for timing marginalities which may result in unstable operation includes: delaying internal address signals of the memory by an amount great enough so that data cannot be validly written to and read from memory locations which are accessed by address signals having timing marginalities which are delayed but small enough so that data can be validly written to and read from memory locations which are accessed by address signals not having such timing marginalities which are delayed. Data is then written to and read from memory locations which are accessed by delayed address signals, and a determination is made as to whether the data read from any memory location does not correspond with the data written to such memory location.

  • Patent number: 7321628
    Abstract: System and method for reducing power consumption and noise in a transmission system with an asymmetrically terminated transmission line. A preferred embodiment comprises encoding data words to reduce the number of times a given state appears in a code word. The preferred embodiment comprises counting the number of times a given state appears in a data word. If the count is greater than half of the total number of bits in the data word, then the data word is inverted and a weight bit can be set to the given state. If the count is less than (or equal to) half of the total number of bits, then the data word may be unchanged and the weight bit can be set to the inverse of the given state. The code word can be generated by appending the weight bit to the data word.

  • Publication number: 20070094554
    Abstract: A test mode for component-specific testing of a memory module. Data is written to and stored in each memory component of a memory module, which data indicates whether the memory component is to execute a particular test mode. Upon receiving a test mode command supplied in common to all of the memory components on the memory module, each memory component examines the data to determine whether it is to execute a test mode command supplied contemporaneously therewith or subsequently supplied test mode commands.

  • Patent number: 7042206
    Abstract: An integrated circuit has connecting pads for outputting digital signals, a connection for a time reference signal, and an assessment circuit to measure and assess a phase shift between one of the digital signals and the time reference signal. A receiver circuit is connected to a respective junction between one of the connecting pads and an associated output driver. A device for matching propagation times of signals applied to the receiver circuit is provided. The assessment circuit is connected to the receiver circuit and has an output to output a measured result. In each case, the phase shift of the signals to be output in relation to the time reference signal is measured and assessed separately. An offset of the switching edges of the signals to be output can be determined relatively accurately and corrected.

  • Patent number: 7019554
    Abstract: An integrated circuit includes at least one main circuit 313 operable to perform one or more functions. At least one termination node DQ receives or transmits an operating signal. An active termination circuit 301 has first and second transistors of opposite type coupled in series between a Vdd node of a first source potential and a Vss node of a second source potential. The at least one termination node is coupled to a common node between the first and second transistors. A control circuit operates to bias the first and second transistors such that they exhibit a controlled impedance at the common node. Alternatively, the control circuit operates to bias the first and second transistors such that they provide a clamping function at the common node.

  • Patent number: 6956409
    Abstract: System and method for detecting a reference signal. A preferred embodiment comprises a latch (such as the latch 320) and a filter (such as the filter 325). The latch tracks a reference signal at its input and reflects the reference signal at its output. The filter can be coupled to the output of the latch and may inject a delay to help eliminate the effects of glitches and noise. When the reference signal reaches a specified value, a control signal from the filter causes the latch to store the reference signal. A delay imparted by the filter ensures that the latch does not store the reference signal until a finite amount of time after the reference signal reaches the specified value.

  • Patent number: 6927709
    Abstract: An N-bit word is produced from an M-bit code received on an M-bit line, M being larger than N, the M-bit code comprising at least an M-bit code word and a previous M-bit code word, the M-bit code word comprising different levels at at least two bit positions, and the previous M-bit code word comprising levels opposite to the different levels at the corresponding bit positions, by comparing the levels at the two bit positions of the M-bit code word to obtain a first value, comparing the levels at the two corresponding bit positions of the previous M-bit code word to obtain a second value, detecting that the first value is opposite to the second value, and decoding the M-bit code word responsive to detecting that the first value is opposite to the second value. An advantage of the present invention is that all the lines taking part in the transmission have the same electrical characteristics, the same meaning and the same kind of loads.
