  • Patent number: 11079954
    Abstract: A deduplication memory system includes a virtual memory space, a physical memory space and a memory manager. The memory manager generates a user data entry that is stored in the physical memory space. The user data entry represents a unique user data of a predetermined granularity appearing in the virtual memory space, and includes first and second portions. The first portion includes information relating to a number of duplication times the unique user data corresponding to the user data entry is duplicated in the virtual memory space, and the second portion includes a selected part of the unique user data from which the unique user data may be reconstructed. The first portion may include an index to an extended reference counter table or a special data pattern table if the number of duplication times of the unique user data is greater than or equal to a predetermined number.

  • Publication number: 20200225862
    Abstract: A memory system provides deduplication of user data in the physical memory space of the system for user data that is duplicated in the virtual memory space of a host system. A transaction manager (TM) uses a transaction table to maintain data coherency and data concurrency for the virtual memory space. A write data engine manager (WDEM) uses an outstanding bucket number and command queues to maintain data coherency and data concurrency for the physical memory space. The WDEM receives data write requests from the TM and sends a corresponding write command to a selected command queue. A write data engine responds to a write command in a command queue by storing the data in an overflow memory region if the data is not duplicated in the virtual memory space, or by incrementing a reference counter for the data if the data is duplicated in the virtual memory space.

  • Patent number: 10705969
    Abstract: A dedupable cache is disclosed. The dedupable cache may include cache memory including both a dedupable read cache and a non-dedupable write buffer. The dedupable cache may also include a deduplication engine to manage reads from and writes to the dedupable read cache, and may return a write status signal indicating whether a write to the dedupable read cache was successful or not. The dedupable cache may also include a cache controller, which may include: a cache hit/miss check to determine whether an address in a request may be found in the dedupable read cache; a hit block to manage data accesses when the requested data may be found in the dedupable read cache; a miss block to manage data accesses when the requested data is not found in the dedupable read cache; and a history storage to store information about accesses to the data in the dedupable read cache.
