  • Publication number: 20250004938
    Abstract: A storage device includes a memory device including a plurality of planes each including a plurality of memory blocks, and a controller configured to group the memory blocks into a plurality of super blocks, each including memory blocks belonging to two or more planes operating in parallel, change mapping information so that a bad block included in a super block to be allocated during super block allocation is replaced with a replacement block of the same plane as the bad block, and delete the mapping information corresponding to the replacement block when an allocated super block is released. The memory blocks are divided into user memory blocks grouped into the super blocks and reserved memory blocks that are not grouped into the super blocks, and the replacement block is selected from memory blocks included in free super blocks of an empty status and the reserved memory blocks.

  • Publication number: 20240201865
    Abstract: A memory system includes a memory device including a plurality of planes each including a plurality of memory blocks; and a memory controller for controlling the memory device to perform an operation on target blocks among the plurality of memory blocks, to store, in a replacement block, data stored in a bad block, on which the operation fails among the target blocks, and control the memory device to temporarily store, in a backup block, data stored in the other blocks except the bad block among the target blocks according to a number of free blocks included in the memory device.
