Abstract: An electronic device comprises a clock request pad, a multiplexer and a control circuit. The clock request pad is arranged to refer to a first control signal to operate under a low voltage level or a high voltage level, to indicate whether the electronic device needs a clock signal generated from a clock generation circuit external to the electronic device. Said multiplexer is arranged to refer to a second control signal to output one of a voltage level of the clock request pad and a predetermined voltage level to function as a multiplexer output signal. The control circuit is coupled to said multiplexer, and refers to said multiplexer output signal to determine whether to control the electronic device to operate in a power-saving mode.

Abstract: A method for performing access management of a memory device in predetermined communications architecture with aid of flexible delay time control and associated apparatus are provided. The method may include: utilizing at least one upper layer controller of a transmission interface circuit within the memory controller to dynamically set a delay parameter regarding transmission from the memory device to a host device, for preventing sleeping in delay time(s) corresponding to the delay parameter; utilizing a physical layer (PHY) circuit of the transmission interface circuit to transmit first data from the memory device to the host device, wherein a first delay time starts from a first time point at which transmitting the first data from the memory device to the host device is completed; and utilizing the PHY circuit to start transmitting second data from the memory device to the host device in the first delay time without restarting from sleeping.
