Abstract
A non-volatile memory system includes a NAND flash memory device including at least one NAND flash memory and a memory controller that controls the NAND flash memory, a host device including a file system and a host controller that receives a command from the file system to provide the command to the NAND flash memory device, and a save storage manager that monitors a number and location of run-time bad blocks in the NAND flash memory, monitors a logical address use-state of the file system, and reduces a logical address space which the file system is able to use as the number of the run-time bad blocks is increased.
