    摘要： A method and system maintains an address table for mapping logical groups to physical addresses in a memory device. The method includes receiving a request to set an entry in the address table and selecting and flushing entries in an address table cache depending on the existence of the entry in the cache and whether the cache meets a flushing threshold criteria. The flushed entries include less than the maximum capacity of the address table cache. The flushing threshold criteria includes whether the address table cache is full or if a page exceeds a threshold of changed entries. The address table and/or the address table cache may be stored in a non-volatile memory and/or a random access memory. Improved performance may result using this method and system due to the reduced number of write operations and time needed to partially flush the address table cache to the address table.

    摘要： A method and system for managing maintenance operations in a multi-bank non-volatile storage device is disclosed. The method includes receiving a data write command and associated data from a host system for storage in the non-volatile storage device and directing a head of the data write command to a first bank in the and a tail of the data write command to a second bank, where the head of the data write command only includes data having logical block addresses preceding logical block addresses of data in the tail of the data write command. When a status of the first bank delays execution of the data write command the controller executes a second bank maintenance procedure in the second bank while the data write command directed to the first and second banks is pending. The system includes a plurality of banks, where each bank may be associated with the same or different controllers, and the one or more controllers are adapted to execute the method noted above.
