摘要： Method and apparatus for securely erasing data from a non-volatile memory, such as but not limited to a flash memory array. In accordance with various embodiments, an extended data set to be sanitized from the memory is identified. The extended data set includes multiple copies of data having a common logical address and different physical addresses within the memory. The extended data set is sanitized in relation to a characterization of the data set. The data sanitizing operation results in the extended data set being purged from the memory and other previously stored data in the memory being retained.

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： Approaches for implementing a controller for a hybrid memory that includes a main memory and a cache for the main memory are discussed. The controller comprises a hierarchy of abstraction layers, wherein each abstraction layer is configured to provide at least one component of a cache management structure. Each pair of abstraction layers utilizes processors communicating through an application programming interface (API). The controller is configured to receive incoming memory access requests from a host processor and to manage outgoing memory access requests routed to the cache using the plurality of abstraction layers.

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： A data structure is formed that references a garbage collection metric for each of a plurality of associated garbage collection units of a flash memory device. Each garbage collection metric is based on one or more device state characteristics of the associated garbage collection unit. In response to a threshold change in the one or more device state variables, a region of interest within the data structure is sorted based on the garbage collection metrics. One or more garbage collection units are selected for garbage collection operations from the sorted region of interest.

摘要： Method and apparatus for verifying whether metadata identifies a most current version of data stored in a memory space. In accordance with various embodiments, a physical location within a first portion of a solid-state memory space is identified by metadata as storing a current version of user data having a selected logical address. A reverse search is performed upon a second portion of the memory space to determine whether the physical address identified by the metadata stores a stale version of the user data, or whether the physical address stores the current version.
