    • PURPOSE: A semiconductor memory device having a delay locked loop(DLL) circuit which can operate in a high frequency and a method for operating the delay locked loop circuit are provided to enable the whole operation by generating a clock having an enough speed to operate the delay locked loop normally without regard to a clock frequency provided from the external. CONSTITUTION: The delay locked loop circuit comprises a ring oscillator(202) enabled by a burn-in mode signal(BURNIN). Output signals(CLK,CLKB) of the ring oscillator are inputted clock pads(220,221) via fuse stages(210,211), and the clock pads are connected to the delay locked loop circuit. The clock pads are set as a CTM pad and a CTMN pad which receives a CTM signal and a CTMN signal from the external. The CTMN signal has an inverted phase of the CTM signal. The delay locked loop circuit generates an internal clock signal operating internal circuit blocks by inputting the CTM signal and the CTMN signal. A DLL control signal generation circuit(204) generates signals(S1',S2') controlling the delay locked loop circuit in response to a power-up signal(VCCHB), a burn-in mode signal(BURN-IN) and signals(S1,S2) provided to drive the delay locked loop circuit in the prior logic circuit.
    • 目的:提供一种具有能够以高频率操作的延迟锁定环(DLL)电路和用于操作延迟锁定环电路的方法的半导体存储器件,以通过产生具有足够速度的时钟来实现整个操作 延迟锁定环通常不考虑从外部提供的时钟频率。 构成:延迟锁定环电路包括通过老化模式信号(BURNIN)使能的环形振荡器(202)。 环形振荡器的输出信号(CLK,CLKB)通过熔丝级(210,211)输入时钟焊盘(220,221),并且时钟焊盘连接到延迟锁定环电路。 时钟焊盘被设置为CTM焊盘和CTMN焊盘,其从外部接收CTM信号和CTMN信号。 CTMN信号具有CTM信号的反相。 延迟锁定环电路通过输入CTM信号和CTMN信号来产生内部电路块的内部时钟信号。 DLL控制信号生成电路(204)响应于上电信号(VCCHB),老化模式信号(BURN-IN)和信号(BURN-IN),产生控制延迟锁定环电路的信号(S1',S2' S1,S2),用于驱动现有逻辑电路中的延迟锁定环电路。
