Claim Rejections - 35 USC § 103
11. 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.
12. Claim(s) 8, 10-18, is/are rejected under 35 U.S.C. 103 as being unpatentable over HALBERT et al (Pub. No.: US 2017/0286197) in view of TAKAHASHI (Pub. No.: US 2019/287640).
13. Regarding claim 8, HALBERT et al teaches the one or more miscorrections (Fig. 3, #320, paragraph [0079]) in the at least one of the plurality of DQs (Fig. 2, #210, Read data 128b, paragraph [0018]) is corrected by a ECC circuit (Fig. 2, #220) of a memory controller.
HALBERT et al is silent with respect to first and second ECC circuits.
TAKAHASHI et al teaches first and second ECC circuits (Fig. 1, #15A, #15B).
