摘要： In case an address is to access a defective memory cell, a defective memory cell in a memory cell area contained in one of paired memory mats is selected in parallel with a redundant memory cell in a redundant memory cell area contained in the other memory mat. At this time of selecting the redundant main word line for selecting the redundant memory cell, there is not required the logical operation for deciding whether or not the redundant use of the access address fed from the outside is proper. For example, the redundant main word line is set to the select level on the basis of a chip select signal. As a result, the drive start timing of the redundant main word line is not delayed in the least from the drive start timing of the main word line. Thus, it is possible to prevent the event that the select drive timing of the redundant sub word line is delayed on account of the delay in the drive timing of the redundant main word line.
摘要翻译：在地址要访问有缺陷的存储单元的情况下，在包含在其中一个存储器堆中的存储单元区域中的有缺陷的存储器单元与冗余存储器单元并联地选择在另一存储器堆中所包含的冗余存储单元区域中。在选择用于选择冗余存储单元的冗余主字线时，不需要用于判断从外部馈送的访问地址的冗余使用是否合适的逻辑操作。例如，基于片选信号将冗余主字线设定为选择电平。结果，冗余主字线的驱动开始定时至少不会从主字线的驱动开始定时延迟。因此，可以防止由于冗余主字线的驱动定时的延迟而使冗余子字线的选择驱动定时被延迟的事件。

摘要： A method for shortening a waiting time from the setting of a sample in a chamber to the stabilisation of the intensity for a secondary ion for SIMS analysis (mass analysis of the secondary ion) using a raster variation method is provided. By approximating so that the difference between time-lapse variations in intensities of the secondary ions sequentially measured for irradiation densities of two different primary ions becomes constant, a method capable of carrying out an accurate measurement of the concentration of an impurity in consideration of background noise despite time-lapse variations in the intensities of the secondary ions is provided.
