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, 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 1-10, 21 and 30-33 are rejected under 35 U.S.C. 103 as being unpatentable over Moon et al. (US Pub # 2021/0225426).
Per MPEP 2111 and 2111.01, the claims are given their broadest reasonable interpretation and the words of the claims are given their plain meaning consistent with the specification without importing claim limitations from the specification.
Regarding independent claim 1, Moon et al. teach a memory device comprising: an alignment data strobing signal generation circuit configured to receive a read identification signal, read channel signal, and internal clock signal (see Fig. 1-2, 11-16, 18 and paragraph 0006-0009, 0034-0043, 0054-0056, 0122-0133, 0137-0154, 0158-0175, unit 214-read data strobe signal RDQS) and to generate an alignment data strobing signal from the internal clock signal when a read operation on a specific pseudo channel of a specific rank is performed based on the read identification signal signal and the read channel signal (see Fig. 1-2, 11-16, 18 and paragraph 0006-0009, 0034-0043, 0054-0056, 0122-0133, 0137-0154, 0158-0175, unit 412-iCMD is alignment data strobing signal); and a core pipe configured to receive the alignment data strobing signal and to output core data output from the specific pseudo channel, based on the alignment data strobing signal (see Fig. 1-2, 11-16, 18 and paragraph 0006-0009, 0034-0043, 0054-0056, 0122-0133, 0137-0154, 0158-0175, based on iCMD to core die, core data output DATA).
Even though Moon et al. teach core die 420, 430 and core data “DATA” but silent exclusively about core pipe.
