Office Action

§102
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 . DETAILED ACTION General Remarks The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 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 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. When responding to this office action, applicants are advised to provide the examiner with line numbers and page numbers in the application and/or references cited to assist the examiner in locating appropriate paragraphs. 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. Applicants seeking an interview with the examiner, including WebEx Video Conferencing, are encouraged to fill out the online Automated Interview Request (AIR) form (http://www.uspto.gov/patent/uspto-automated-interview-request-air-form.html). See MPEP §502.03, §713.01(II) and Interview Practice for additional details. Applicant's cooperation is requested in correcting any errors of which applicant may become aware in the specification. Status of claim to be treated in this office action: Independent: 1 and 19. b. Claims 1-20 are pending on the application. Drawings 2. The drawings were received on 09/03/2024. These drawings are review and accepted by examiner. Priority 3. Receipt is acknowledged of papers submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Information Disclosure Statement 4. Acknowledgment is made of applicant’s Information Disclosure Statement (IDS) Form PTO-1449; filed 12/13/2024. The information disclosed therein was considered. Specification 5. Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words. It is important that the abstract not exceed 150 words in length since the space provided for the abstract on the computer tape used by the printer is limited. The form and legal phraseology often used in patent claims, such as "means" and "said," should be avoided. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, "The disclosure concerns," "The disclosure defined by this invention," "The disclosure describes," etc. The abstract of the disclosure is objected to because it uses the phrase “OF THE DICLOSURE” in page 1, line 1, which is implied. Correction is required. See MPEP § 608.01(b). 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 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. 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)(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. 6.

Allowable Subject Matter 7. Claims 3-5, 7-18 and 20, insofar as in compliance with the rejection above, 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. The following is a statement of reasons for the indication of allowable subject matter: The cited are, whether taken singularly or in combination, especially when all limitations are considered within the claimed specific combination, fail to teach or render obvious of the remaining claimed limitations. With respected to dependents claims 3-5, the prior art fails to tech or suggest the claimed limitations, namely, the voltage generation circuit, wherein the second circuit is configured to generate the sensing result based on a second current that is proportional to the first current, wherein the second circuit is configured to generate the sensing result by comparing the second current with a reference current, wherein the second circuit is configured to output a first sensing result when the second current is higher than the reference current, and a second sensing result when the second current is equal to or lower than the reference current, and the first circuit stops the boosting of the first voltage in response to the first sensing result and does not stop the boosting of the first voltage in response to the second sensing result. With respected to dependents claims 7-16, the prior art fails to tech or suggest the claimed limitations, namely, the voltage generation circuit, wherein the second circuit includes: a second transistor including a gate to which the reference voltage is applied, a first terminal to which the power voltage is applied, and a second terminal that is connected to a second node; an operational amplifier including a first input terminal to which the first voltage at the first node is applied, a second input terminal to which a third voltage at the second node is applied, and an output terminal from which the operational amplifier outputs a fourth voltage based on the first voltage and the third voltage; a third transistor including a gate to which a fifth voltage based on the fourth voltage is applied, a first terminal that is connected to the second node, and a second terminal that is connected to a third node; a current source that supplies a reference current to a fourth node; a fourth transistor including a gate to which the fifth voltage is applied, a first terminal that is connected to the fourth node, and a second terminal that is connected to a fifth node; and an inverter including an input terminal to which a sixth voltage at the fourth node is applied and an output terminal from which the inverter outputs a second signal based on the sixth voltage, wherein the sensing result is a signal that is generated by the second circuit based on the second signal. With respected to dependents claims 17-18, the prior art fails to tech or suggest the claimed limitations, namely, the voltage generation circuit, wherein the first circuit is configured to stop the boosting of the first voltage based further on a fourth signal that is generated based on the second voltage, further comprising a third circuit including a first terminal to which the sensing result is input, a second terminal to which the fourth signal is input, and a third terminal, wherein the third circuit is configured to calculate a logical product of the sensing result and the fourth signal and output the calculated logical product through the third terminal, wherein the first circuit is configured to stop the boosting of the first voltage based on the calculated logical product. With respected to dependents claim 20, the prior art fails to tech or suggest the claimed limitations, namely, the semiconductor memory device, further comprising a fourth circuit configured to control the voltage generating circuit, wherein the fourth circuit generates a control signal for enabling the second circuit to sense the first current and transmits the control signal to the voltage generation circuit.
