    摘要: A clock gating circuit includes a first precharge unit charging a first node based on a clock signal, a second precharge unit charging a second node based on the clock signal, a first discharge unit discharging the first node based on the clock signal, a second discharge unit discharging the second node based on the clock signal, a first cross-coupled maintain unit maintaining the first node at a charge state according to a voltage level of the second node, a second cross-coupled maintain unit maintaining the second node at a charge state according to a voltage level of the first node, and a control unit controlling the first and second discharge units to discharge the first node or the second node on the basis of a clock enable signal.

    摘要: The timing of the synchronous interface is controlled by a clock signal driven by a controller. The clock is toggled in order to send a command to a memory device via the interface. If there are no additional commands to be sent via the interface, the controller suspends the clock signal. When the memory device is ready, the memory device drives a signal back to the controller. The timing of this signal is not dependent upon the clock signal. Receipt of this signal by the controller indicates that the memory device is ready and the clock signal should be resumed so that a status of the command can be returned via the interface, or another command issued via the interface.
