    • A semiconductor memory device has a single input terminal to select a buffer and includes input-output terminals, input-output buffers, a memory core, and a buffer selecting unit. The input-output terminals include address input terminals, data input-output terminals and an input terminal to select a buffer. The input-output buffers are coupled to the data input-output terminals respectively. The memory core is coupled to the input-output buffers through input-output lines. The buffer selecting unit generates a parallel buffer select signal based on an expected signal having a pulse stream, wherein the expected signal is provided via the input terminal to select a buffer in a test mode, and applies the parallel buffer select signal to the plurality of input-output buffers to select a corresponding input-output buffer. Hence, the semiconductor memory device may increase efficiency of a pin in a test device.
    • 半导体存储器件具有用于选择缓冲器的单个输入端子,并且包括输入 - 输出端子,输入 - 输出缓冲器,存储器核心和缓冲器选择单元。 输入输出端子包括地址输入端子,数据输入输出端子和用于选择缓冲器的输入端子。 输入输出缓冲器分别耦合到数据输入 - 输出端。 存储器内核通过输入 - 输出线耦合到输入 - 输出缓冲器。 缓冲器选择单元基于具有脉冲流的预期信号产生并行缓冲器选择信号,其中经由输入端子提供期望信号以在测试模式中选择缓冲器,并将并行缓冲器选择信号施加到多个 输入 - 输出缓冲区来选择相应的输入 - 输出缓冲区。 因此,半导体存储器件可以提高测试装置中的引脚的效率。
