More Information
Summary:A nonvolatile memory system may include a nonvolatile memory device, a delegate page attacker, and a health status analyzer. The nonvolatile memory device may include at least one memory block including a plurality of storage pages and a delegate page. The delegate page attacker may be configured to attack a bit of the delegate page at the same corresponding location as a bit of the storage page in which an error occurs. The health status analyzer may be configured to perform write and read operations for the delegate page and analyzes error information occurred in the write and read operations to determine whether the nonvolatile memory device is in a failure status.
