摘要:
A wordline decoder circuit and method of decoding a wordline input signal are provided. A first decoder receives multiple inputs to be evaluated. The first decoder includes a first precharge device for precharging a first node and a first discharge device to enable discharging the first node. A first clock signal enables the first discharge device. The first clock signal disables the precharge device. A clock delay circuit receives the first clock signal and generates a delayed clock signal. A second logic is coupled to the first decoder. The second logic provides a wordline output. The second logic wordline output is enabled responsive to the delayed clock signal and is disabled responsive to the first clock signal.
