    • To count the fails in a fail memory (250) with a semiconductor memory tester, data of a plurality of bits are read from the memory (250) and the fails are counted in parallel, thus shortening the time taken to count the fails. A counter for counting the fails of a fail memory has a fail memory block (358) and a fail counter (360). In performing MUT measurement, the fail memory block (358) is regarded as a single memory and data are written therein; in counting fails, the fail memory block (358) is divided into M sub-blocks and M bits of data are read parallel. The M-bit data are inputted into the fail counter (360). The number of logical high or low levels of the data is encoded into binary code data and counted by the fail counter (360).
    • 为了通过半导体存储器测试器对故障存储器(250)中的故障进行计数,从存储器(250)读取多个位的数据,并行计数故障,从而缩短了计数失败所花费的时间。 用于计数故障存储器故障的计数器具有故障存储器块(358)和故障计数器(360)。 在执行MUT测量时,故障存储器块(358)被视为单个存储器并且数据被写入其中; 在计数失败时,故障存储器块(358)被分成M个子块,M个数据位被并行读取。 M位数据被输入失败计数器(360)。 数据的逻辑高或低电平的数量被编码成二进制代码数据并由故障计数器计数(360)。

    • This invention introduces, as one aspect, an apparatus for creating three-dimensional object model, comprising photographing means for photographing an object to be modeled for obtaining images to be used for creating the three-dimensional object model, setting means for longitudinally and latitudinally setting a relative position between the object and said photographing means, said setting means being capable of setting the object and said photographing means a plurality of different relative longitudinal and latitudinal positions, and control means for controlling said photographing means and said setting means so that a number of photographs taken from different relative longitudinal positions at a first relative latitudinal position is larger than that taken from different relative longitudinal positions at a second relative latitudinal position, the first relative latitudinal position being closer to a lateral position than the second relative latitudinal position. Accordingly, it becomes possible to minimize the number of photographs for obtaining necessary images to effectively keep a high quality three-dimensional object model, the number of user's manual operations is reduced, and the total photographing time for creating a three-dimensional object model is significantly decreased.
