Abstract
A memory system or flash memory device may include a linking or grouping of blocks that are used for dual writing. In particular, meta-blocks in the memory may be linked in such a way that enables a data transfer to simultaneously occur in two meta-blocks. The dual versions of the programming may be used for error correction. If there is a failure or write error in one of the meta-blocks, then the data from the other meta-block may be used. If there is no failure then the secondary meta-block may be erased.
