摘要： Provided are a method and apparatus for remapping logical to physical addresses for a non-volatile memory having dies. Bands extend through the dies and planes in the dies extending through the bands define addressable blocks. A first remapping of a logical-to-physical mapping is performed by remapping logical addresses of blocks in a first end of the bands that map to defective physical blocks to map to good physical blocks at a second end of the bands. After performing the first remapping, a second remapping of the logical-to-physical mapping is performed by remapping logical addresses in the second end of bands that map to defective blocks to map to good physical blocks in the first end of bands.
