The adjacent planes include a reserve field and a data field having multiple blocks. The blocks of each of the reserve and data fields are successively arranged over the adjacent planes to form a multi-plane operation group. The control module is configured to control the adjacent planes to conduct a first operation or a second operation in accordance with whether the reserve field includes free blocks corresponding to a unit of the multi-plane operation group. The first operation includes replacing blocks of the data field with free blocks of the reserve field in the unit of the multi-plane operation group. The second operation includes replacing one block of the data field with one free block of the reserve field. | 03-05-2009 |
