Abstract
Provided herein is a memory system and a method for driving the memory system. The memory system may include: a semiconductor memory device including a plurality of memory blocks and a block information storing block; and a controller configured to control the semiconductor memory device to store block information about the memory blocks into the block information storing block during an overall operation of the semiconductor memory device, and perform, during a power loss recovery operation, a recovery operation using the block information stored in the block information storing block.
Claims20
A memory system comprising:
- a semiconductor memory device including a plurality of memory blocks and a block information storing block;
- and
- a controller configured to:
- control the semiconductor memory device to store block information about the memory blocks into the block information storing block during an overall operation of the semiconductor memory device, and
- perform, during a power loss recovery operation, a recovery operation using the block information stored in the block information storing block.
A memory system comprising:
- a semiconductor memory device including a plurality of memory blocks and a block information storing block;
- and
- a controller configured to control the semiconductor memory device to store block information about the memory blocks into the block information storing block at each of status update points at which statuses of the memory blocks are changed during an overall operation of the semiconductor memory device.
A method of operating a memory system, comprising:
- performing an overall operation including a read operation, a write operation, and an erase operation of a semiconductor memory device including a plurality of memory blocks and a block information storing block;
- updating and storing block information into the block information storing block at each of status update points during the overall operation;
- reading latest block information stored in the block information storing block when a power-on operation is performed after a power loss;
- and
- performing a power loss recovery operation using the read latest block information.
