Office Action

§103
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 . Claims 1-20 are pending. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. Claim(s) 1- 20 are rejected under 35 U.S.C. 103 as being unpatentable over Tanzawa (US2023017005) in view of Song et al (US20230066757) hereinafter Song.

Memory cells MCA, and MCB are coupled to the output by the selection line, SE. Fig. 4 illustrates associated buffer 180 coupled to the controller to the cells via pad such as pad2 to the cell array, paras. 0074 – 0076).

(0006). As to claim 2, Tanzawa discloses the memory device, wherein the first data signal is associated with a first one or more of the memory cells and the second data signal is associated with a second one or more of the memory cells (Fig. 2, and paras. 0022, 0023). As to claims 3, and 17, Tanzawa discloses the memory device, wherein the sense amplifier circuitry is configured to store data associated with a second one or more of the memory cells within the buffer circuitry (Fig. 13, where buffer circuit module 180 coupled to sense amplifier 120, and cells, 110), and para. 22). As to claim 4, Tanzawa discloses the memory device, wherein the first data signal is associated with a first read command and the second data signal is associated with a second read command (Fig. 2, and paras. 0024, 0025 where the common buffer 15 is used detailing a read command). As to claims 5, and 18, Tanzawa discloses the memory device, wherein the sense amplifier circuitry is configured to store data associated with a third read command within the buffer circuitry (Fig. 3, and para. 0028, where buffer 17 captures data to store).
