A non-volatile memory system is formed a plurality of memory banks and a controller, where the controller has an auxiliary memory interface for use with an additionally non-volatile memory bank, where the additional memory bank and interface are used for metadata, such as logical to physical translation data. The other banks are used for user data. In an exemplary embodiment, a non-volatile memory could include a controller and (N+1) NAND flash memories, where N of these memories would store user data, but the remaining memory with its own controller interface would be dedicated to the storage of metadata. This allows for the metadata to be kept in non-volatile memory, but still quite readily accessible relative to the typical paging/overlay arrangement for metadata that is typically used in many non-volatile memory system.
