Abstract
A flash memory system and managing and collecting methods for flash memory with invalid page messages thereof are described. When the valid data pages of the flash memory are changed to invalid data pages, a recording area is used to record the message of the invalid data pages to effectively collect the occupied space of the invalid data pages in the flash memory. Further, while garbage collecting step is performed, a block is rapidly selected according to the message of the recording area and the valid data pages in the selected block are correctly identified, copied and removed.
