Abstract
The block groups of a multiple data channel flash memory storage device are detected for defective blocks. The block group containing any defective blocks is divided into subgroups, each of which contains only defective blocks or only good blocks. The subgroups containing only good blocks are selected to establish a new block group having the same amount of blocks as that of the original block groups.
