Abstract
A flash memory controller is disclosed. The flash memory controller is configured to access a flash memory module, wherein the flash memory module includes a plurality of first blocks and a plurality of second blocks, and the flash memory controller includes a microprocessor and a read-only memory storing a program code. When the flash memory controller is powered on, when the flash memory controller is required to write data into the flash memory module, the microprocessor writes the data into the plurality of first blocks only; and the microprocessor writes subsequent data into the second blocks only when a quantity of the plurality of first blocks written by the flash memory controller after power on is greater than a threshold value.
