A controller located in a memory device includes a feedback regulation circuit. The feedback regulation circuit is configured to generate a feedback voltage to a power supply circuit according to a power consumption of the controller, for the power supply circuit to adjust an input voltage input to the memory device according to the feedback voltage. When the power consumption of the controller is lower, the feedback voltage is higher, so that the input voltage is lower, and when the power consumption of the controller is higher, the feedback voltage is lower, so that the input voltage is higher.

Controller, memory device and control method for adjusting power consumption

A USB switching circuit includes a first multiplexer, a second multiplexer coupled with the first multiplexer through transmission paths, and a voltage regulation circuit coupled with the first and second multiplexers. The first multiplexer distributes first data signals to the transmission paths according to first control signals. The second multiplexer distributes a second data signal to the transmission paths according to second control signals. The voltage regulation circuit sets a maximum voltage and a minimum voltage of the first data signals to corresponding to a common voltage. The maximum voltage of the first data signals is not higher than a maximum voltage of the second control signals, or the minimum voltage of the first data signals is not lower than a minimum voltage of the second control signals. The first data signals and the second data signal are generated according to different communication protocols.
