    摘要： A second impurity diffusion layer is formed in a semiconductor substrate at a fixed distance from a first diffusion layer in the substrate. The diffusion layer is supplied with a program potential. An electrode is placed on the channel region between the first and second diffusion layers. Non-selected memory cells are prevented from becoming half-selected by electrically separating the first diffusion layer from the program potential according to signals from the electrode, resulting in substantial improvements in the reliability of the semiconductor device.

    摘要： An electric power steering device for a vehicle includes a plurality of assist systems electromagnetically driving an electric motor. When a first or second assist system malfunctions, a malfunction state assist amount calculation part calculates an assist amount while decreasing a limit value at the vehicle stopping, to an amount smaller than a limit value at the vehicle moving. When a malfunction such as a disconnection or a fixing of the switching elements occurs in the first or second assist systems on the basis of a judgment result of a malfunction judgment function, an assist amount switching part supplies an assist amount received from the malfunction state assist amount calculation part to first and second motor drive control parts. When a malfunction occurs in one of the first and second assist systems, one of the first and second motor drive control parts drives the motor by using the assist amount.

    摘要： The ratio of the angular speed of a pinion shaft to the angular speed of a steering wheel is computed. The steering torque Tst transferred to the steering wheel is computed as a multiplication product of the ratio of angular speed and the steering torque Tm of the pinion shaft. The steering torque ΔTst transferred to the steering wheel due to actuation of a steered wheel turning angle variable device is computed as a value obtained by subtracting the steering torque Tm from the steering torque Tst. An electric power steering control device is controlled so as to generate a steering torque fluctuation-reducing assist torque corresponding to the steering torque ΔTst.
