    • A circuit for controlling latency by using a queuing design scheme and a method thereof are provided to reduce the number of registers used in controlling the latency, a layout area and power consumption. A circuit for controlling latency by using a queuing design scheme comprises an FIFO controller(310) and a register unit(330). The FIFO controller(310) generates an increased signal by an external command in response to a clock signal, generates a decreased signal by an internal command, and activates one among depth point signals in response to the increased signal and the decreased signal. The register unit(330), comprising registers for shifting previous addresses, stores an address inputted with the external command in response to the increased signal, and outputs addresses stored at the registers in correspondence with the activated depth signal.
    • 提供了一种通过使用排队设计方案及其方法来控制等待时间的电路,以减少用于控制等待时间,布局面积和功耗的寄存器数量。 通过使用排队设计方案来控制等待时间的电路包括FIFO控制器(310)和寄存器单元(330)。 FIFO控制器(310)响应于时钟信号通过外部命令产生增加的信号,通过内部命令产生减小的信号,并响应于增加的信号和减小的信号激活深度信号中的一个信号。 寄存器单元(330)包括用于移位先前地址的寄存器,响应于增加的信号存储输入了外部命令的地址,并且根据激活的深度信号输出存储在寄存器中的地址。
