摘要： In a MOS integrated circuit is provided a first differential amplifying circuit for receiving complementary sets of input data at the gates of its two p-channel MOS transistors and for transmitting complementary sets of internal data. There is also provided a second differential amplifying circuit for receiving the complementary sets of internal data at the gates of its two n-channel MOS transistors and for transmitting complementary sets of output data. This realizes high-speed data transmission in which data transmission speed is independent of the generation of a clock signal. By preventing the flow of current from a power supply terminal to a ground terminal, a differential transmission circuit which consumes reduced current can be obtained.

摘要： In a dynamic random access memory including a plurality of memory read circuit arrays, a sense amplifier has a circuit wherein a first switch (or a pair of first switches) and a pair of second switches connected in series to the first switch are connected between the common data lines and the common source line of a second precharger. The first switch is controlled according to the potential of the bit lines precharged by a first precharger, while the second switches are controlled according to the address signal. Further, a third switch is provided to connect the common source line to an activation potential for the common source line in the memory array not selected. A second precharger precharges the common source line in a memory array not selected to a second precharge potential and the common data lines in a memory array not selected to a third precharge potential during the time when the common source line and the common data lines are not selected. The first, second and the third precharge potentials are set so as to prevent a through current through the third switch. Alternatively, the third switch may be omitted by providing appropriate precharge potentials.

摘要： In a dynamic random access memory of precharge type including a plurality of memory arrays, switches provided for a memory array connect one of the common source lines of a sense amplifier with common data lines is always turned on in a non-selected memory array. The switch is kept turned on even in a period wherein the memory array is selected and the sense amplifier is kept active. When the one of the common source lines is connected by the switches, the potential of the one of the common source lines increases and the potentials of the common data lines also increase without a pull-up circuit. The precharge potentials to be supplied to the common source lines may be different from each other. Further, a load circuit may be provided for each memory array for loading the common data lines for reading information when a switch is turned off to isolate the common data lines. Then, the read and write actions can be stabilized.

摘要： A brushless DC motor having a rotor magnet magnetized to provide a sinusoidal magnetic field and two-phase stator windings at positions which differ from each other by an electrical angle which is an odd multiple of 90.degree. is provided with a drive circuit comprising a signal generator with an output having a frequency determined by the rotational speed of the rotor, and a memory having stored therein digital information data converted from sampled values of a sinusoidal signal free of distortion. The digital information data stored in the memory is read out therefrom by the output of the signal generator in synchronism with the magnetic field from the rotor magnet, and such read-out information data is employed to determine currents flowing through the stator windings so that torque ripple is substantially eliminated.

The second transistor is connected with a complementary write bit line, the write word line, and a second output node of the second inverter. The third transistor is connected with a read bit line, a read word line, and the first input node of the first inverter to form a read port transistor, and a read port is formed.
