ABSTRACT:
A storage apparatus and an accessing method for the storage apparatus are provided. The storage apparatus comprises a plurality of data blocks, a plurality of spare blocks, and a calculation apparatus. The calculation apparatus is configured to (1) confirm whether a written block has to be updated, (2) select one of the spare blocks as the first moving block, (3) select one of the data blocks as second moving block, (4) store the first data of the second moving block into the first moving block, and (5) store the second data related to the written block into the second moving block. By updating a written block, data stored in other blocks are moved between each other. Blocks are charged and discharged so that data in the blocks are more accurate. The lifetime of the storage apparatus can be increased as well.
