Abstract
A method of operating a storage device having a nonvolatile memory including at least one memory block having a plurality of sub-blocks includes reading backup data of backup memory cells having a highest program state among a plurality of memory cells connected to at least one word line of a sub-block which is not erase-requested adjacent to an erase-requested sub-block among the sub-blocks. The method includes storing the backup data, erasing the erase-requested sub-block, and reprogramming the backup memory cells having the highest program state on the basis of the backup data.
