    • Various embodiments of a delay locked loop circuit of a semiconductor memory apparatus are disclosed. In one exemplary embodiment, the delay locked loop circuit may include an input correction unit configured to correct a duty ratio of an input clock based on a duty control signal and generate a reference clock; a delay line configured to delay the reference clock by a delay time and generate a delay locked clock; an output correction unit configured to correct a duty ratio of the delay locked clock based on the duty control signal and generate a corrected clock; and a control signal generation unit configured to generate the duty control signal when a correction activation signal is enabled.
    • 公开了半导体存储装置的延迟锁定环电路的各种实施例。 在一个示例性实施例中,延迟锁定环电路可以包括:输入校正单元,被配置为基于占空比控制信号校正输入时钟的占空比并产生参考时钟; 延迟线,被配置为将所述参考时钟延迟延迟时间并产生延迟锁定时钟; 输出校正单元,被配置为基于所述占空比控制信号校正所述延迟锁定时钟的占空比,并生成校正时钟; 以及控制信号生成单元,被配置为当校正激活信号被使能时产生占空比控制信号。
