摘要： A DLL of a memory device having a normal mode and a power down mode includes a clock buffer for buffering an external clock signal to output an internal clock signal. A power down mode controller generates a power down mode control signal to define the normal mode or the power down mode in response to a clock enable signal. A source clock generation unit receives the internal clock signal to generate a DLL source clock signal under the control of the power down mode control signal. A phase update unit performs a phase update operation based on the DLL source clock signal to output a DLL clock signal.

摘要： A method, apparatus and system for pre-authenticating ports is disclosed. In one embodiment, an active port facilitating communication of media content between a transmitting device and a receiving device is identified, while the active port are associated with a first High-Definition Content Protection (HDCP) engine. Then, inactive ports that are in idle mode serving as backup ports to the active port are identified, while the inactive ports are associated with a second HDCP engine. Pre-authentication of each of the inactive ports is performed so the pre-authenticated inactive ports can subsequently replace the active port if a port switch is performed.

摘要： A current sense amplifier may include one or more clamping circuits coupled between differential output nodes of the amplifier. The clamping circuits may be enabled during at least a portion of the time that the sense amplifier is sensing the state of a memory cell coupled to a differential input of the sense amplifier. The clamping circuits may be disabled during the time that the sense amplifier is sensing the state of a memory cell at different times in a staggered manner. The clamping circuits may be effecting in making the current sense amplifier less sensitive to noise signals.
