  • De-duplication as part of other routinely performed processes
    Patent number: 9626121
    Abstract: A mechanism is provided for performing de-duplication process on a set of non-volatile memories as part of another process routinely performed on the set of non-volatile memories. A hash value of data stored at a first physical location in a non-volatile memory in the set of non-volatile memories is received from a non-volatile memory controller associated with the non-volatile memory. Responsive to the hash value matching one or more existing hash values for data stored at one or more other physical locations in the set of non-volatile memories, an optimal physical location is identified from the first physical location and the one or more other physical locations. Responsive to identifying the optimal physical location, a set of logical addresses associated with the hash values is updated to point to the optimal physical location. The non-optimal physical locations are further invalidated in order that the non-optimal physical locations are erased.
