摘要： In a magnetic-field angle detection device and a rotation angle detection device in which the accuracy of the measured angle is not degraded even if the MR ratio of the tunneling magnetoresistance element is increased. In a magnetic-field-angle measurement apparatus including a magnetic-field-angle detection circuit and a magnetic sensor having a tunneling magnetoresistance element with a pinned magnetic layer, the magnetic-field-angle detection circuit has a power-supply unit that outputs a constant voltage as a bias voltage to the tunneling magnetoresistance element of the magnetic sensor and a current-detection unit that detects an output current of the tunneling magnetoresistance element. The accuracy of the measured angle of the magnetic-field angle detection device and the rotation angle detection device is improved by measuring the tunneling magnetoresistance element current while maintaining the terminal voltage of the tunneling magnetoresistance element constant with input impedance of the current-detection unit as zero.

摘要： A semiconductor memory comprises a write driver which is provided to correspond to respective data line and by which data lines connected with a memory cell through the control of a word line are driven in a write operation. The write driver includes MOSFETs of first group and MOSFETs of second group. In a case where a write enable signal does not designate the write operation, the MOSFETs of the first group are normally in ON states to pull up the data lines. Besides, in a case where the write enable signal designates the write operation, each of them operates in accordance with the value of input data, to maintain the ON states and pull up the corresponding data line in case of driving the data line to a "high" level and to fall into OFF states in case of driving the data line to a "low" level. On the other hand, the MOSFETs of the second group are normally in OFF states. Besides, in the case where the write enable signal designates the write operation, each of them operates in accordance with the value of the input data, to fall into ON state and draw the corresponding data line to the low level in the case of driving the data lines to the low level.
