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.

Method and computer-readable storage medium and apparatus for adjusting operating frequencies

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.

Method and computer program product and apparatus for adjusting operating frequencies

The present invention provides a flash memory controller, wherein the flash memory controller is arranged to access a flash memory module, the flash memory module includes a plurality of flash memory chips, the flash memory controller includes a buffer memory and a microcontroller, and the buffer memory is arranged to store an in-system programming (ISP) code. When the flash memory controller enters a power saving mode, the microcontroller disables a portion of the buffer memory to make at least one portion of the ISP code disappear; and when the flash memory controller enters a normal mode from the power saving mode, the microcontroller reads said at least one portion of the ISP code from N flash memory chips within the plurality of flash memory chips, wherein N is a positive integer greater than one.

Flash memory controller, control method of flash memory controller and associated electronic device

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.
