Abstract:
A data storage apparatus executes a garbage collection method. The data storage apparatus includes a NAND flash memory including blocks each of which includes pages. In the garbage collection method, a destination block is selected from the blocks. Mapping tables and a relevance bitmap are built before writing user data into the destination block. Each bit in the relevance bitmap is related to one of the mapping tables. A victim block is selected from the blocks. Some of the mapping tables are read according to the relevance bitmap for the victim block. It is determined whether if the pages, one after another, of the victim block are in the read mapping tables. The page is set to be a valid page if a page of the victim block is in a read mapping table. Data in the valid pages is written into another block.

Claim (Index 3):
The garbage collection method according to  claim 2 , wherein step (gl) comprises the steps of:\n (g 1 A) setting some of the bits of the valid-page bitmap ( 20 ) related to the valid pages to be \u201c1\u201d; and (g 1 B) setting the other bits of the valid-page bitmap ( 20 ) to be \u201c0.\u201d
