Abstract: The invention introduces a non-transitory computer program product for adjusting operating frequencies when executed by a processing unit of a device, containing program code to: collect an interface-activity parameter comprising information about data transmissions on a host access interface and/or a flash access interface; select one from multiple frequencies according to the interface-activity parameter; and drive a clock generator to output a clock signal at the selected frequency, thereby enabling the host access interface and/or the flash access interface to operate at an operating frequency.

Abstract: The invention introduces a method for resetting a flash memory device, performed by a controller of a host, including at least the following steps: driving a memory controller to perform fewer than a maximum number of normal resets after receiving a hardware reset command from a processor; and driving the memory controller to perform a super reset when the normal resets are unsuccessful.

Abstract: The invention introduces a non-transitory computer-readable storage medium for adjusting operating frequencies when executed by a processing unit of a device, containing program code to: collect an interface-activity parameter comprising information about data transmissions on a host access interface and/or a flash access interface; select one from multiple frequencies according to the interface-activity parameter; and drive a clock generator to output a clock signal at the selected frequency, thereby enabling the host access interface and/or the flash access interface to operate at an operating frequency.

Abstract: A storage device including a volatile memory, a non-volatile memory and a controller is provided. The controller sends a plurality of commands to the non-volatile memory. When the controller receives a reset signal, the controller determines whether a specific operation has been completed. When the controller has not yet finished the specific operation, the controller continuously provides the commands to the non-volatile memory. When the controller has finished the specific operation, the controller performs a reset operation according to the reset signal.
