Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1 and 19 are rejected under 35 U.S.C. 103(a) as being disclosed by Chen et al. (US 11,614,478 hereinafter referred to as Chen), and further in view of Jang et al. (US PGPUB 2009/0310412 hereinafter referred to as Jang) in view of Derzhavetz et al. (US 11,615,028 hereinafter referred to as Derzhavetz).
As per independent claim 1, Chen discloses a storage device supporting a flush operation among multiple namespaces [(Column 4, lines 41-56 and Column 7, lines 36-56; FIGs. 2 and 6A and related text) wherein Chen teaches where FIG. 2 is a schematic diagram of the namespace table (NST) 112, the index table (IDXT) 114, and a logic-to-physical table (L2PT) 116 in the internal memory 104 and the memory array 106 according to an embodiment of the present invention. In the embodiment of FIG. 2, the NST 112 includes a plurality of namespace identifiers (NSIDs) and at least one internal NSID (i.e., “m-1” of NSID) in first column, and the NST 112 further includes a start entry and an end entry of the IDXT 114 shown as (“start entry”, “end entry”) in second column for each NSIDs and the at least one internal NSID; the processor flushes the latest mapping data in the internal memory 104 not store at the memory array yet to the memory array 106. In step S620, the processor updates the start entry and the end entry of the IDXT 114 (i.e., (0, 0) of mark 651 in part (B) of FIG. 6B) with the narrowed size “1” according to the third NSID “0” in the NST 112, and the processor updates all of the start entry and the end entry of the IDXT 114 (i.e., (1, 1) of mark 652 in part (B) of FIG. 6B). The narrowed size “1” is predetermined by the memory controller, and the narrowed size“1” is smaller than a size between the original entry and the original end entry (0, 1) of the IDXT 112. In step S630, the processor arranges the entries in the IDXT 114 according to the narrowed size “1”. For example, the entry “1” of IDXT 114 in part (A) of FIG. 6B has been deleted, and the original entries “0”, “2”-“4” of IDXT 114 in part (A) of FIG. 6B has been moved to the entries “0”-“3” of IDXT 114 in part (B) of FIG. 6B shown as mark 654. Then, in step S640, the processor flushes flushing latest mapping data in the internal memory not store at the memory array yet to the memory array again to correspond to the claimed limitation], the storage device comprising: a volatile memory configured to temporarily store a plurality of pieces of data received from a host device; a non-volatile memory device comprising a plurality of namespaces [(Column 3, lines 41-46, Column 4, lines 41-56 and Column 7, lines 36-56; FIGs. , 2 and 6A and related text) wherein Chen teaches where the memory device 100 is a storage device. For example, the memory device 100 can be an embedded multimedia card (eMMC), a secure digital (SD) card, a solid-state drive (SSD), or some other suitable storage; FIG. 2 is a schematic diagram of the namespace table (NST) 112, the index table (IDXT) 114, and a logic-to-physical table (L2PT) 116 in the internal memory 104 and the memory array 106 according to an embodiment of the present invention. In the embodiment of FIG. 2, the NST 112 includes a plurality of namespace identifiers (NSIDs) and at least one internal NSID (i.e., “m-1” of NSID) in first column, and the NST 112 further includes a start entry and an end entry of the IDXT 114 shown as (“start entry”, “end entry”) in second column for each NSIDs and the at least one internal NSID; the processor flushes the latest mapping data in the internal memory 104 not store at the memory array yet to the memory array 106. to correspond to the claimed limitation]; and a controller configured to perform a flush operation in response to a flush command received from the host device [(Column 5, lines 60-65, Column 6, lines 30-56 and Column 7, lines 36-56; FIGs. 2 and 6A and related text) wherein Chen teaches where the FIG. 3 is a flow chart illustrating a method for accessing the memory device according to an embodiment of the present invention. Referring to FIG. 1 to FIG. 3, in step S310 of FIG. 3, the memory controller 102 of the memory device 100 obtains the data access command from the host device 101 to determine whether a data of the data access command contains one of the NSIDs, the processor flushes latest mapping data in the internal memory 104 not store at the memory array 106 yet to the memory array 109 to correspond to the claimed limitation], wherein the controller is further configured to, in the flush operation, move at least one piece of data, stored in the volatile memory and corresponding to the flush command, to at least one of the plurality of namespaces of the non-volatile memory device in a unit smaller than or equal to a namespace [(Column 7, lines 36-56; FIG. 6A and related text) wherein Chen teaches where the storage device supporting a flush operation among multiple namespaces, the storage device comprising: a volatile memory configured to temporarily store a plurality of pieces of data received from a host device; a non-volatile memory device comprising a plurality of namespaces; and a controller configured to perform a flush operation in response to a flush command received from the host device, wherein the controller is further configured to, in the flush operation, move at least one piece of data, stored in the volatile memory and corresponding to the flush command, to at least one of the plurality of namespaces of the non-volatile memory device in a unit smaller than or equal to a namespace to correspond to the claimed limitation].
Chen does not appear to explicitly disclose wherein the controller is further configured to, in the flush operation, move at least one piece of data, stored in the volatile memory and corresponding to the flush command, to at least one of the plurality of namespaces of the non-volatile memory device in a unit smaller than or equal to a namespace.
However, Jang discloses wherein the controller is further configured to, in the flush operation, move at least one piece of data, stored in the volatile memory and corresponding to the flush command [(Paragraph 0046; FIGs. 1 and 3) where Jang teaches where FIG. 1 is a block diagram illustrating a data flush operation according to some embodiments. Referring to FIG. 1, an information processing system 10 may include a host 20 and a memory card 50. The memory card 50 responds to a command CMD from the host 20 to store data from the host 20 in a first non-volatile memory module 30. During a flush operation, the memory card 50 rearranges sector data C, 2, A, 1, and B sequentially stored in the first non-volatile memory 30 so as to be divided into groups G1 and G2, and stores the groups G1 and G2 of the sector data in a second non-volatile memory module 40 to correspond to the claimed limitation], to at least one of the plurality of namespaces of the non-volatile memory device in a unit smaller than or equal to a namespace [(Paragraphs 0048, 0050 and 0059; FIGs. 1 and 3) where Jang teaches where sector data C, 2, A, 1, and B input in the first non-volatile memory 30 in a FIFO manner may be divided into groups G1 and G2. The groups G1 and G2 of sector data may be flushed into the second non-volatile memory 40 group-by-group according to a respective priority associated therewith, which may reduce the number of merge operations performed to transfer the data to the second non-volatile memory 40; flush operation may proceed as follows. In the following example, each data block of the second non-volatile memory 150 has 50 sectors. Accordingly, sector data may be grouped by a 50.sup.th unit. In a case where sector data is grouped by a 50.sup.th unit, sector data between a 0.sup.th sector and a 49.sup.th sector may constitute one group. And, sector data between a 50.sup.th sector and a 99.sup.th sector may constitute another group to correspond to the claimed limitation].
Chen and Jang are analogous art because they are from the same field of endeavor of data storage management.
Before the effective filing date of the claimed inventions, it would have been obvious to one of ordinary skill in the art, having the teachings of Chen and Jang before him or her, to modify the method of Chen to include the flushing of data in a unit smaller than or equal to the namespace of Jang because it will enhance apparatus efficiency.
The motivation for doing so would be [“increase the speed and/or life of a memory system that includes different non-volatile memories; reduce the number of merge operations and/or erase counts below that which may be possible via a host driver of the host 20 or a flash translation layer FTL of a conventional memory card 50” (Paragraphs 0007 and 0048 by Jang)].
Chen does not appear to explicitly disclose the flush command comprising information on a type of a data unit on which the flush operation is to be performed.
However, Derzhavetz discloses the flush command comprising information on a type of a data unit on which the flush operation is to be performed [(Column 20, lines 40-50) where Jang teaches where the Lockless destaging process 10 may determine that, because the current tablet identifier for metadata page 1102 indicates that metadata page 1102 read from data array 112 is newer than the metadata data page to destage (e.g., based upon, at least in part, current tablet identifier 1104 for metadata page 1102 read from data array 112 and the plurality of destage tablets (e.g., tablets 604 and 606) that have not been destaged to metadata page 1102), destaging the metadata deltas of tablets 604 and 606 is moot. Accordingly, lockless destaging process 10 may skip 416 destage request 1100. to correspond to the claimed limitation].
Chen and Derzhavetz are analogous art because they are from the same field of endeavor of data storage management.
Before the effective filing date of the claimed inventions, it would have been obvious to one of ordinary skill in the art, having the teachings of Chen and Derzhavetz before him or her, to modify the method of Chen to include the flush command that include identifiers of Derzhavetz because it will enhance apparatus efficiency.
The motivation for doing so would be [“there will also be a marked improvement in throughput and response times ” (Column 8, lines 62-66 by Derzhavetz)].
Therefore, it would have been obvious to combine Chen, Jang and Derzhavetz to obtain the invention as specified in the instant claim.
As for independent claim 19, the applicant is directed to the rejections to claim 1 set forth above, as they are rejected based on the same rationale.
