摘要： In the early half of one period of a main clock, one multiplexer selects a signal Ain, while the other multiplexer selects an inverted signal /Ain. Consequently, the signal Ain is transmitted to a signal line assigned to the signal line Ain, while the signal /Ain is transmitted to a signal line assigned to a signal Bin, thereby accomplishing differential transmission of the signal Ain. In the late half of one period of the main clock, the above one multiplexer selects an inverted signal /Bin, while the above other multiplexer selects the signal Bin. Consequently, the inverted signal /Bin is transmitted to the signal line assigned to the signal Ain, while the signal Bin is transmitted to the signal line assigned to the signal Bin, thereby accomplishing differential transmission of the signal Bin. Since differential transmission is thus accomplished with no increase in the number of wires, power saving can be achieved by data transfer with a small amplitude.

摘要： In transmitting a first pair of differential clock signals UCLK, UXCLK having an extremely small amplitude voltage based on a power-source potential and a second pair of differential clock signals LCLK, LXCLK having an extremely small amplitude voltage based on the power-source potential, an inverting circuit as a signal receiving circuit is composed of a CMOS inverting circuit. A PMOS transistor composing the CMOS inverting circuit has a gate electrode and a source electrode receiving the first pair of differential clock signals. An NMOS transistor composing the CMOS inverting circuit has a gate electrode and a source electrode receiving the second pair of differential clock signals. When the potentials of the differential clock signals change, potentials at the respective gate and source electrodes of the two transistors shift in opposite directions, which surely cuts off the transistors. Accordingly, the signal receiving circuit composed of the inverting circuit operates statically in response to the first and second pairs of differential signals.

摘要： Two multiplexors select a first signal Ain and its inverted signal /Ain in the first half of a single cycle of a clock signal and Ain and /Ain, i.e., a differential signal pair, are differential-transmitted to two signal lines. On the other hand, the two multiplexors select a second signal Bin and its inverted signal /Bin in the second half and Bin and /Bin, i.e., a differential signal pair, are differential-transmitted to the two signal lines. Based on the transition probability of Ain and Bin or based on the mode information of a system, either Ain or Bin is selected and is differential-transmitted. As a result of such arrangement, when the transmission of one of Ain and Bin is not required, the other signal can continuously be differential-transmitted using an unoccupied signal line, which makes it possible to increase the rate of signal transmission without having to increase the number of signal lines.

摘要： An exclusive OR circuit is provided which detects whether or not a preceding-stage logical output value and a subsequent-stage logical output value agree. When these logical output values are found to agree, a NAND circuit functions to cut off the supply of a clock signal to a first and second switch circuits and to a latch circuit. Accordingly, when there occur no data changes between clock signal cycles, in a switch circuit and a latch circuit both arranged between each stage of a pipeline, the charge/discharge of the capacitance of gate electrodes of transistors forming these circuits is prevented, thereby reducing power consumption.

摘要： In a signal transmission circuit having a plurality of signal lines for supplying potentials to load capacitances, in which each load capacitance is driven by each signal line, each signal line can be connected to another signal line via a switch. By connecting two signal lines at different potentials to each other by means of said switch, the potentials of the signal lines are changed through the process of charge redistribution, thereby eliminating charging and discharging through a power-source line and a ground line. Therefore, if n load capacitances are equal to each other, the switches are controlled so that the potential variation of each of the signal lines is phase shifted from those of its adjacent signal lines by 1/n. Thus, the load capacitances can be driven with 1/n of the total amount of charge consumed in the case of driving the n load capacitances independently, thereby reducing the consumed current.

摘要： Precharge circuits precharge plural pairs of bit lines to a specified potential when no word line is selected (during standby). Pull-down transistors are turned ON when the corresponding word lines are not selected so as to connect the corresponding word lines to a common power source line, which is connected to the ground. In a path connecting the above common power source line to the ground is disposed an impedance changing means for changing the impedance of the path between a value during standby and another valve during operation during which any word line is selected so that the value during standby is set higher than the value during operation. Consequently, during standby, a leakage current (standby current) resulting from a short circuit between a bit line and a word line is reduced.
