Abstract
A non-volatile storage system is configured to reclaim bad blocks. One embodiment includes determining that a block of non-volatile memory cells is a bad block, leaving the block idle for a period of time to allow for self-curing of the block, verifying success of the self-curing, refreshing the block, verifying that the refresh was successful and subsequently using the block to store host data.
