    摘要: Methods and systems are disclosed to generate a data map for a data storage device. A data map may be generated by scanning, during a power-on initialization process, data units of data stored on a data storage medium of a data storage device. The scanning may start from a selected data unit and proceed through the data units in an order opposite to a write order to identify a first data unit that is not fully erased. Also. an error recovery status of the first data unit may be determined based on an error correction code. A likely erased status of the first data unit may be assigned when the determined error recovery status is unrecoverable.

    摘要: This disclosure is related to systems and methods for selective metadata storage in a system having multiple memories. In one example, a device may include a control circuit configured to selectively store a metadata base map in a first memory or a second memory. The metadata base map may include information to determine a physical memory address from a logical block address. The control circuit may also be configured to store metadata updates separately from the metadata base map. The metadata updates may comprise changes to the metadata base map. The control circuit may also be configured to selectively store the metadata updates in the first memory or the second memory based on characteristics of the device.

    摘要: This disclosure is related to systems and methods for a structured mapping system for a memory device, such as a solid state data storage device. In one example, a data storage device may include a multi-level address mapping system. The multi-level address mapping system may be implemented completely independent of a host computer and a host computer operating system. Also, the multi-level mapping system may be stored to allow each level, or subsets of each level, to be re-written independently of the other levels or the other subsets.
