Abstract:
A memory system, including a flash memory including multiple memory blocks, and a controller configured to erase each of the memory blocks using multiple steps. The controller stores, for each of the memory blocks, metadata indicating which of the multiple steps have been completed, and erases each of the memory blocks based on the stored metadata.
