Abstract
A memory system includes a memory device, a system memory, and a controller. The memory device includes a page storing a first chunk including first user data and first meta data and a second chunk including second user data and second meta data. The system memory stores an address map table for a physical address of the page in which the first chunk and the second chunk are stored and a logical address mapped to the physical address. The controller is configured to perform a read operation of the page by recovering the first meta data using the physical address of the first chunk and the address map table, and outputting the second user data using the second meta data of the second chunk on which an error correction operation has passed, when an error correction operation on the first chunk has failed.
