Abstract:
The present invention provides a flash memory controller, wherein the flash memory controller is arranged to access a flash memory module, and the flash memory controller includes a ROM, a microprocessor and a timer. The ROM stores a program code, the microprocessor is configured to execute the program code to control the access of the flash memory module, and the timer is used to generate time information. In the operations of the flash memory controller, the microprocessor refers to the time information to perform dummy read operations upon at least a portion of the blocks, wherein the dummy read operations are not triggered by read commands from a host device.
