Abstract
A flash memory controller includes a recording medium and a processing circuit. When the amount of stored data in a flash memory module is less than a first threshold, the processing circuit controls a read and write circuit of the flash memory module to program a target data block using program threshold voltages within a first voltage range so as to write data into the target data block. When the amount of stored data in the flash memory module is greater than a second threshold, the processing circuit controls the read and write circuit to program the target data block using program threshold voltages within a second voltage range so as to write data into the target data block, wherein the second threshold is greater than the first threshold and the first voltage range is less than the second voltage range.
