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.

摘要： Apparatus and method for data management in a memory, such as but not limited to a flash memory array. In accordance with some embodiments, a plurality of data sets in a memory are identified as having a common data content and different physical addresses in the memory. A selected one of the data sets is marked as valid data and the remaining data sets are marked as stale data responsive to evaluation of at least one variable parameter associated with the physical addresses at which the data sets are respectively stored.

摘要： A method and apparatus for rebuilding a data set. In accordance with some embodiments, a data storage device is coupled to a host. An error condition associated with a memory of the data storage device is detected. Data stored in a first portion of the memory unaffected by said error condition is transferred to the host. A communication signal is output to the host that indicates that data stored in a second portion of the memory affected by said error condition will not be transferred to the host. The host reconstructs the data stored in the second portion of the memory responsive to the communication signal.

摘要： Method and apparatus for managing data in a memory, such as a flash memory array. In accordance with various embodiments, data are stored in a first location in a memory, and read from the first location a selected number of times. At least one parameter associated with the first location is measured after the data are read the selected number of times. The data are thereafter migrated to a second location in the memory responsive to the measured parameter indicating a presence of read disturbance in the data in the first location.

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 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 data in a memory, such as a flash memory array. In accordance with some embodiments, a first block of data is written to a group of memory cells at a first memory location in single-level cell (SLC) mode. The first block of data is copied from the first memory location to a group of memory cells at a second memory location to provide a backup copy of the first block of data during a protected mode of operation. A second block of data is subsequently overwritten to the group of memory cells at the first memory location so that the first memory location stores both the first and second blocks of data in multi-level cell (MLC) mode.
