    • A semiconductor device includes a section signal generator and a decoder. The section signal generator generates a section signal by retarding a pre-section signal including a pulse created during a read operation or a write operation by a delay time that is set according to a level combination of first and second test mode signals. The decoder decodes address signals in response to a pulse of the section signal to generate column selection signals, one of which is selectively enabled, to store an external data in a memory cell of an internal circuit or to output a data stored in a memory cell of an internal circuit.
    • 半导体器件包括部分信号发生器和解码器。 区段信号发生器通过将包括在读取操作或写入操作期间产生的脉冲的预分段信号延迟根据第一和第二测试模式信号的电平组合设置的延迟时间来产生分段信号。 解码器响应于区段信号的脉冲对地址信号进行解码,以产生列选择信号,其中一个被选择性地使能,以将外部数据存储在内部电路的存储单元中,或者输出存储在存储单元中的数据 的内部电路。

    • A data input circuit includes a clock sampling unit, a final clock generation unit, and a write latch signal generation unit. The sampling unit is configured to generate a shifting signal including a pulse generated after a write latency is elapsed, and generate a sampling clock by sampling an internal clock during a burst period from substantially a time when the pulse of the shifting signal is generated. The final clock generation unit is configured to generate a level signal by latching the shifting signal in synchronization with the sampling clock and generate a final clock from the level signal in response to a burst signal. The write latch signal generation unit is configured to generate an enable signal by latching the final clock and generate a write latch signal for latching and outputting aligned data in response to the enable signal.
    • 数据输入电路包括时钟采样单元,最终时钟产生单元和写入锁存信号产生单元。 采样单元被配置为产生包括在写入等待时间之后产生的脉冲的移位信号,并且在从产生移位信号的脉冲的时间开始的脉冲串周期期间,通过对内部时钟进行采样来产生采样时钟。 最终时钟生成单元被配置为通过与采样时钟同步地锁存移位信号来产生电平信号,并且响应于突发信号从电平信号产生最终时钟。 写锁存信号生成单元被配置为通过锁存最终时钟来产生使能信号,并且响应于使能信号产生用于锁存和输出对准数据的写锁存信号。
