摘要： An object of the present invention is to reduce jitter dependent on data patterns by an interface receiver. Another object of the present invention is to provide an LSI capable of automatically adjusting a delay time for jitter reduction so as to be able to control its setting for each device. Since the jitter dependent on the data patterns can be expected according to how the previous state is being placed, the state of data received by the receiver is held, and the timing provided to fetch input data is adjusted according to the held state and the input data. As a control mechanism lying in the receiver, for determining a delay time dependent on the form of mounting, a driver transmits and receives pulse data set at one-cycle intervals and pulse data set at two-cycle intervals as test patterns. The receiver has an automatic control mechanism for determining a delay time optimal to a system from the difference between a rising time of each of pulses different in pulse width and its falling time.

摘要： A dummy wiring 25 is provided for simulating an actual wiring 26 connecting semiconductor integrated circuits 2 and 6 on a circuit board. The semiconductor integrated circuit comprises a data output circuit 28 capable of variably setting the slew rate and a circuit 29 for measuring signal delay time between a signal sending point and a signal reflection point (characteristic impedance mismatching point) using the dummy wiring 25, and the delay time so obtained by the measuring circuit is used for the determination of the signal transition time of the output circuit. The transition time of the signal is set at least twice of the signal delay time between the signal sending point and the wiring branch at the nearest end. In this way, signal transmission with alleviated reflection by the reflection point at the nearest end is realized.

摘要： There is the problem that since C/A signals in a DIMM are distributed to respective DRAMs through a register in the DIMM and DQ signals are wired directly from terminals in the DIMM, their timing is difficult to synchronize. The register for speeding up the C/A signals of the DIMM that operates with high speed is provided, and a wiring from the register is set to a daisy-chain wiring. Then, by a timing adjustment circuit provided in the DRAM, a wiring delay time difference between the C/A signals and the clock signals, which are different depending on positions of the DRAMs, is such that the sum of a delay time from the register to each DRAM and a delay amount due to the timing adjustment circuit is made equal to a delay time of the farthest DRAM.
