    • A method for testing a memory cell array of a semiconductor memory device in a parallel bit test mode includes selecting first data from one of a plurality of memory regions in the memory array for output from the memory device via an input/output pad, and then selecting second data from another of the plurality of memory regions for output via the input/output pad. The first and second data can be selected from memory regions sharing a row select or a column select control line. Alternatively, one of the first and second data can be selected from memory regions sharing a row select control line, and the other can be selected from memory regions sharing a column select control line. Therefore, a parallel bit test can be performed using fewer input/output pads, and a larger number of semiconductor memory devices can simultaneously be tested. Related circuits are also discussed.
    • 用于以并行位测试模式测试半导体存储器件的存储单元阵列的方法包括从存储器阵列中的多个存储器区域之一中选择第一数据,以经由输入/输出焊盘从存储器件输出,然后 从所述多个存储器区域中的另一个存储区域中选择第二数据,以经由所述输入/输出焊盘输出。 可以从共享行选择或列选择控制线的存储器区域中选择第一和第二数据。 或者,可以从共享行选择控制线的存储器区域中选择第一和第二数据中的一个,并且另一个可以从共享列选择控制线的存储器区域中选择。 因此,可以使用更少的输入/输出焊盘来执行并行位测试,并且可以同时测试更多数量的半导体存储器件。 还讨论了相关电路。
