Abstract
According to one embodiment, a memory system includes: a nonvolatile memory including blocks each of which includes physical memory areas; and a memory controller dividing a logical address space into a plurality of banks and associating a block with each of the plurality of banks. The memory controller is configured to: selectively scan a portion related to a first bank among the plurality of banks in a table in which a physical address corresponding to a physical memory area in which valid data is stored is mapped on the logical address space; detect a first physical address corresponding to a first physical memory area in a first block associated with the first bank as a result of the scan; read first valid data stored in the first block based on the first physical address; and write the first valid data in a second block associated with the first bank.
