摘要： The optical disc apparatus according to the present invention includes a tilt detecting means; a coma aberration correcting means; and a spherical aberration correcting means. Based on the result of a tilt detection, the amount of the correction performed by the coma aberration correcting means is determined so that the amount of correction is constant for the whole circumference of an optical disc, and then a spherical aberration is corrected by the spherical aberration correcting means. Thus, it is possible to correct the spherical aberration that has occurred due to the coma aberration correcting means, while the tilt margin is secured, thereby improving the reliability of reproduction and recording by the optical disc apparatus. Further, the optical disc apparatus according to the present invention is configured, in the case where a thermal shock tilt has occurred during the activation of the apparatus, to wait until the thermal shock tilt has settled. Thus, it is possible to perform the activation while the influence of the thermal shock tilt is avoided, thereby improving the reliability of the recording and reproduction operations by the optical disc apparatus.

摘要： First dummy memory cells connected to a first dummy signal line have the same shape and characteristics as those of a real memory cell. The first dummy memory cells are arranged to be adjacent to outermost real memory cells. A voltage setting circuit changes the voltage of the first dummy signal line from a first voltage to a second voltage in order to write test data onto the first dummy memory cell during a test mode. By writing data of a logic opposite to that of the test data onto the real memory cell adjacent to the first dummy memory cell by means of an operation control circuit, a leak failure that may occur between the first dummy memory cell and the real memory cell adjacent thereto can be checked.

摘要： A register part of a mode register has a plurality of operation setting parts in which plural types of operating specifications are respectively set to operate the semiconductor memory. The mode register outputs a soft reset signal when at least a value of one-bit of the register part represents a reset state. A reset signal generator outputs a reset signal for resetting an internal circuit in response to the soft reset signal. In the present invention, a system that controls the semiconductor memory is required to necessarily assign a predetermined bit with a setting command of the mode register in order to generate the soft reset signal. Accordingly, it is possible to reliably reset the internal circuit by external control.
