    摘要: In a prior art, there has been a method in which a power supply line of an output buffer and that of a control circuit are independently provided so that the power supply noise occurring in the control circuit will not affect the output buffer. However, this method has had the problems that it increases both the number of power supply/grounding pins and power feed line inductance.The present invention provides a technique which, without causing the above two problems, i.e., (1) increased number of power supply/grounding pins and (2) increased power feed line inductance, prevents the noise causing a problem in a control circuit, from becoming routed around and induced into an output buffer. More specifically, the above can be realized by using either of two methods: (A) providing an on-chip bypass capacitor for the control circuit and isolating a power feed route of the control circuit from that of the output buffer in an AC-like manner, or (B) designing electrical parameters (inserting resistors) such that the oscillation mode of any electrical parameter noise induced into the power feed routes will change to overdamping.

    摘要: A clock is located at a position close to a plurality of memory modules connected to a memory controller and located away from the controller, and wiring is carried out so that read access is preferential for transmission of read data. With respect to write data, a delay amount corresponding to a round-trip propagation delay time to each of the modules is measured and writing of the write data is carried out while maintaining a known time relationship between the clock and data. To measure round-trip reflection, lines are wired between the modules and a location detection circuit in a 1:1 relationship, and the circuit measures a time taken from a signal output time of a driver having the same impedance as that of the wired lines to a reflected-wave reception time of a hysteresis receiver.

    摘要: A printed circuit board with reduced noise effects and without the need to increase the distance between a noise source and a wireless communication board. The circuit board includes multilayer structural conductive layers having a first conductive plane connected to power supply potential and a second conductive plane connected to ground potential. The first and second conductive planes are formed such that an electric field generated by a potential difference between the first conductive plane and the second conductive plane is concentrated on one side of one of the first conductive plane and the second conductive plane. The conductive plane associated with the concentrated electric field and the wireless communication board are on different sides relative to the conductive plane that is not associated with the concentrated electric field.

    摘要: A fast transfer bus system capable of fast data transfer with no reflection at branch points. Four LSIs having constant-impedance interfaces are connected via two variable resistors each having three signal terminals. A variable impedance LSI is connected between these variable resistors. When the LSIs connected to the variable resistor do not work as a bus driver, three variable resistance elements in each variable resistor are set to have a value of ⅓ of the characteristic impedance Zo of connection lines, and are connected in a Y-letter shape. When one of LSIs connected to the variable resistor works as a bus driver, the values of the variable resistance elements are set to low impedance or Zo.
