Abstract: Systems, methods and/or devices are used to enable enhancing data integrity to protect against returning old versions of data. In one aspect, the method includes (1) receiving a write request from a host that specifies write data for a set of logical block addresses in a logical address space of the host, (2) mapping the set of logical block addresses to a set of physical addresses corresponding to physical pages of the storage device, and (3) performing one or more operations for each logical block specified by the set of logical block addresses, including: (a) generating metadata for the logical block, the metadata including a version number for the logical block, (b) storing the metadata, including the version number, in a header of a physical page in which the logical block is stored, and (c) storing the version number in a version data structure.

Abstract: Systems, methods and/or devices are used to enhance data integrity to protect against returning old versions of data. In one aspect, a method includes (1) receiving a write request from a host that specifies write data for a set of logical block addresses, (2) mapping, using a mapping table, the set of logical block addresses to a set of physical addresses, where the mapping table includes a plurality of subsets, and (3) performing operations for each subset of the mapping table that includes at least one entry corresponding to a logical block specified by the set of logical block addresses, including: (a) generating metadata for the subset, the metadata including a version number for the subset, (b) calculating a Cyclic Redundancy Check (CRC) checksum for the subset, and (c) storing the version number for the subset and the CRC checksum for the subset in a version data structure.

Abstract: A non-volatile memory controller coordinates multiple datapath units along a datapath between a host side and a memory side by unit-to-unit communication, or by a datapath control unit that is in communication with multiple datapath units. Data of a data stream is prioritized so that it passes along the datapath without interruption.

Abstract: Buffer memory reservation techniques for use with NAND flash memory include dynamically reserving regions of the buffer memory, responsive to a read/write request. Where the read/write request includes a plurality of data transfer requests, following completion of a data transfer request, the reserved buffer space may be recycled for use in a further data transfer request or for other purposes. During fulfillment of a read request, a buffer region is reserved from a larger buffer pool for a time period significantly smaller than the time required to execute a sense operation associated with the read request. The reserved buffer region may be reused for unrelated processes during execution of the sense operation.

Abstract: This disclosure provides examples of circuits, devices, systems, and methods for managing a buffer memory. Regions of the buffer memory are dynamically reserved, responsive to a read/write request. Where the read/write request includes a plurality of data transfer requests, following completion of a data transfer request, the reserved buffer space may be recycled for use in a further data transfer request or for other purposes. During fulfillment of a read request, a buffer region is reserved from a larger buffer pool for a time period significantly smaller than the time required to execute a sense operation associated with the read request. The reserved buffer region may be reused for unrelated processes during execution of the sense operation.
