Office Action

§102 §112
DETAILED ACTION 1. Claims 1-20 are pending in this application. Notice of Pre-AIA or AIA Status 2. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . IDS 3. The information disclosure statement filed on April 9, 2026 fails to comply with 37 CFR 1.98(a)(3)(i) because it does not include a concise explanation of the relevance, as it is presently understood by the individual designated in 37 CFR 1.56(c) most knowledgeable about the content of the information, of each reference listed that is not in the English language. It has been placed in the application file, but the information referred to therein has not been considered. Claim Rejections - 35 USC § 112 4. The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. 5. Claim 10 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The claim recites the limitation “adjacent ones of the plurality of first memory cells are commonly connected to a common memory resistor.” This limitation requires memory cells with two adjacent memory cells to be commonly connected to two common memory resistors, one on each side. There’s no disclosure of memory transistors with two common memory resistors. Claim Rejections - 35 USC § 102 6. 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)(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. 7. Claims 1, 3-4, 9, and 11 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by US Pat. No. 12,277,990 (“Chang”). 8. With respect to claim 1, Chang discloses a memory device (FIG. 1, 100), comprising: a memory array (104, rows WLm–WL1) including a plurality of first memory cells (103) physically arranged over a plurality of rows and a plurality of first columns, wherein each of the plurality of first memory cells includes a memory transistor serially coupled to a memory resistor (342 is serially coupled to 372; also note that 352 is serially coupled to 372 through 342); and one additional row (WL0) arranged next to the memory array, wherein the one additional row includes a plurality of first shunt components (FIG. 3, M1-M6; the examiner notes that while Chang does not call these components “shunt components”, they are structurally indistinguishable from the claimed “shunt components”), and wherein each of the plurality of first shunt components includes a shunt transistor (322) and a shunt resistor (362); wherein respective first source/drain terminals of the shunt transistors of the plurality of first shunt components are electrically coupled to one another (both terminals of each of the transistors in row 0, i.e., WL0, are connected other terminals of other transistors in the memory array, for example all transistor terminals of word line 0 are electrically coupled in series through transistors 342, 344 … 342n, 344n and resistors 372, 274 … 372n, 374n), and respective second source/drain terminals of the shunt transistors of the plurality of first shunt components are electrically coupled to one another and further electrically coupled to respective first source/drain terminals of the memory transistors of the plurality of first memory cells (transistor terminals of word line 0 are connected to transistors of other word lines through bit lines BL0-BLm, bit lines are also electrically coupled to other bit lines through SG transistors 302, 304 … 302n, 304n and mux transistors 382 … 382n). 9.

With respect to claim 11, see the rejection of claims 1, 3, and 4 above. 13. Claims 1, 3-6, 9, 11-16, and 18-20 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by US Pub. 2009/0225586 (“Ueda”). 14.
