DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Allowable Subject Matter
Claim(s) 2-10, 12-16 and 18-20 is/are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim(s) 1, 11 and 17 is/are rejected under 35 U.S.C. 102(a)(1) and (a)(2) as being anticipated by Khawand (US 2012/0096225).
Regarding claim(s) 1, 11 and 17, Khawand teaches:
A method, comprising: configuring, in a local memory of a memory sub-system, a read buffer and a write buffer having a first ratio between a capacity of the read buffer and a capacity of the write buffer; buffering, in the read buffer, data communicated between the memory sub-system and a host system in association with read commands from the host system; buffering, in the write buffer, data communicated between the memory sub-system and the host system in association with write commands from the host system; [0046] The computing device 200 comprises cache ram 270 that has memory space allocated to a read cache 280 and a write cache 290. The read cache 280 and write cache 290 are separate caches, with the read cache 280 storing only data from read operations involving storage devices and the write cache 290 storing data only for write operations involving storage devices.
and determining statistics of read commands and write commands received in the memory sub-system during a first time period; [0043] In some implementations, the computing device 110 automatically and dynamically adjusts the read cache size of the read cache 130 and the write cache size of the write cache 140. For example, the read cache size and write cache size can be adjusted based on cache performance parameters comprising preference scores for cache blocks read and/or written (e.g., via an API), the frequency of read requests and the frequency of write requests, the read and write performance of the storage device 150, localization information, and/or contiguous read and write performance.
identifying, based at least in part on the statistics, a second ratio between the capacity of the read buffer and the capacity of the write buffer. [0043] In some implementations, the computing device 110 automatically and dynamically adjusts the read cache size of the read cache 130 and the write cache size of the write cache 140. For example, the read cache size and write cache size can be adjusted based on cache performance parameters comprising preference scores for cache blocks read and/or written (e.g., via an API), the frequency of read requests and the frequency of write requests, the read and write performance of the storage device 150, localization information, and/or contiguous read and write performance.
Response to Arguments
Applicant's arguments filed 8/12/2026 have been fully considered but they are not persuasive.
In page 4, applicant argues:
“Specifically, Khawand fails to disclose identifying, based at least in part on the statistics, a second ratio between the capacity of the read buffer and the capacity of the write buffer, as claimed by Applicant. Rather, Khawand is limited to disclosing data from storage devices is stored in a read cache, having a read cache size, and a write cache, having a write cache size. The read cache and the write cache are separate caches. Cache configuration of the read cache and the write cache are automatically and dynamically adjusted based, at least in part, upon cache performance parameters. Cache performance parameters include one or more of preference scores, frequency of read and write operations, read and write performance of a storage device, localization information, and contiguous read and write performance. Dynamic cache configuration includes one or more of adjusting read cache size and/or write cache size and adjusting read cache block size and/or write cache block size.”
The Examiner respectfully disagrees. The read cache and the write cache of Khawand can be interpreted as being parts of a local memory/cache system of a computing device just as the read buffer and write buffer are part of the local memory of the memory sub-system. The limitation “identifying… a second ratio between the capacity of the read buffer and the capacity of the write buffer” is interpreted to include Khawand’s identifying and adjusting of the read cache size or the write cache size based on read/write performance or frequencies.
Conclusion
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
