摘要
A flash memory device with a wear-levelining mechanism includes at least one flash memory, a hot list, a bitmap, a source pointer, and a controller. The controller obtains a physical memory block with high erase count through the hot list, an erase count of the physical memory block, and an overall average erase count of the flash memory device. The controller further finds out a physical memory block which stores static data through managing the bitmap and the source pointer. The controller moves the static data to the physical memory block with high erase count, and releases the physical memory block which stores the static data to avoid the physical memory block with high erase count being worn down increasingly more seriously.
