Abstract
Method for writing data into flash memory is disclosed. The method includes storing the frequently updated data and the not-aligned data collectively into some of the physical memory blocks of the flash memory. In other words, the method collectively writes those data into the same physical memory blocks of the flash memory as far as possible. By doing this, the invalid physical memory pages in the physical memory blocks can be generated collectively. As a result, the storage releasing efficiency of garbage collection can be greatly improved.
