    • A delay circuit for internal clock generation in a dynamic RAM uses a one-shot multivibrator composed of a pair of cross-coupled CMOS NOR gates with a RC delay circuit in the coupling path between the output of one NOR gate and the input of the other. The RC delay circuit uses an MOS transistor as the resistor, with the gate of this device connected to the supply voltage, so the resistance varies with changes in the supply. A CMOS inverter stage in the delay circuit has its input connected across the capacitor of the RC delay, so the trip point will vary with threshold voltage. In a dynamic RAM, this circuit may be used to establish the critical timing between write and read mode.
    • 用于动态RAM中内部时钟产生的延迟电路使用由一对交叉耦合的CMOS或非门组成的单稳态多谐振荡器,其中一个或非门的输出与另一个或非门的输入之间的耦合路径中具有RC延迟电路 。 RC延迟电路使用MOS晶体管作为电阻,该器件的栅极连接到电源电压,因此电阻随电源的变化而变化。 延迟电路中的CMOS反相器级的输入端连接在RC延迟的电容器两端,因此跳变点将随阈值电压而变化。 在动态RAM中,该电路可用于建立写入和读取模式之间的关键定时。
