Summary:Methods, systems and devices provide for refreshing a data image stored on a NAND memory device. Aspects include sequentially copying each of a series of static data partitions into a scrub portion that does not store data image partitions identified in the partition table. The sequential copying begins with a last static data partition and proceeds sequentially to a first static data partition when the scrub portion occupies higher order addresses than the last address of the last static data partition. Alternatively, the sequential copying begins with the first static data partition and proceeds sequentially to the last static data partition when the scrub portion occupies addresses that are lower than the first address of the first static data partition. The partition table may be updated as each static data partition is stored to the scrub portion. Such operations enable fail-safe scrubbing and refreshing of data in a NAND device. 方法、系统和设备提供了刷新存储在NAND存储器设备上的数据镜像。诸方面包括将一系列静态数据分区中的每个分区顺序地复制到未存储在分区表中标识出的数据镜像
