摘要： Method and apparatus for ensuring a most recent version of data is retrieved from a memory, such as a non-volatile flash memory array. In accordance with various embodiments, a controller is adapted to sequentially store different versions of an addressable data block having a selected logical address in different locations within a memory. The controller assigns a revision indication value to each said version, with at least two of said stored versions concurrently sharing the same revision indication value. In some embodiments, the revision indication value constitutes a repeating cyclical sequence count that is appended to each block, or logically combined with a code value and stored with each block. The total number of counts in the sequence is less than the total number of versions resident in the memory.

摘要： Method and apparatus for handling data in a data storage device. In accordance with some embodiments, a memory space with a plurality of garbage collection units (GCUs) that are each arranged into pages of memory that store user data identified by logical addresses (LAs) and each GCU has a metadata region that stores metadata that correlates the LAs with physical addresses (PAs). A header region in each page of memory stores a bitmask and a sequence map of the LAs in each page that are used by a log manager to creates a bitmask table stored in a first cache and a hierarchical log stored in a second cache. The bitmask table and hierarchical log are used to determine when the LAs stored in the selected GCU are stale, and update the bitmask for each page in the selected GCU after the stale data has been erased.

摘要： A new segment of data is copied to a volatile, primary cache based on a host data read access request. The primary cache mirrors a first portion of a non-volatile main storage criterion is determined for movement of data from the primary cache to a non-volatile, secondary cache that mirrors a second portion of the main storage. The criterion gives higher priority to segments having addresses not yet selected for reading by the host. In response to the new segment of data being copied to the primary cache, a selected segment of data is copied from the primary cache to the secondary cache in response to the selected segment satisfying the criterion.

摘要： Method and apparatus for maintaining data integrity in a data storage device. In accordance with some embodiments, a memory space has a plurality of garbage collection units (GCUs) each arranged to store user data identified by logical addresses. Each GCU has a metadata region that stores metadata that correlates the logical addresses LBAs with physical addresses and a header region that stores descriptor data that identifies LBAs stored in the associated GCU. A control circuit identifies an error in the metadata from the descriptor data of a selected GCU and rebuilds the metadata to indicate a storage location of a most current version of data associated with a selected logical address.

摘要： Method and apparatus for managing metadata associated with a data storage array. In accordance with various embodiments, a group of user data blocks are stored to memory cells at a selected physical address of the array. A multi-tiered metadata scheme is used to generate metadata which describes the selected physical address of the user data blocks. The multi-tiered metadata scheme provides an upper tier metadata format adapted for groups of N user data blocks, and a lower tier metadata format adapted for groups of M user data blocks where M is less than N. The generated metadata is formatted in accordance with a selected one of the upper or lower tier metadata formats in relation to a total number of the user data blocks in the group.

摘要： Host read operations affecting a first logical block address of a data storage device are tracked. The data storage device includes a main storage and a non-volatile cache that mirrors a portion of data of the main storage. One or more criteria associated with the host read operations are determined. The criteria are indicative of future read requests of second logical block address associated with the first logical block address. Data of the at least the second logical block address is copied from the main storage to the non-volatile cache if the criteria meets a threshold.
