Patent number: 11942180Abstract: A memory system includes semiconductor memory devices and a control device. Each of the semiconductor memory devices includes a first pad to which a first signal is input, a second pad to which a second signal is input, a third pad to which a third signal is input, a memory cell array, a sense amplifier, and a data register. In a first mode, after the first signal is switched, a command set instructing a data out operation is input via the second pad. In a second mode, after the first signal is switched, the command is input via at least the third pad. The control device executes a first operation assigning different addresses to the respective semiconductor memory devices and a second operation causing the modes of the respective semiconductor memory devices to be switched from the first to the second mode.Type: GrantFiled: June 27, 2022Date of Patent: March 26, 2024Assignee: KIOXIA CORPORATIONInventors: Zhao Lyu, Akio Sugahara, Takehisa Kurosawa, Yuji Nagai, Hisashi Fujikawa

Publication number: 20240094959Abstract: A semiconductor memory device comprises: a first pad receiving a first signal; a second pad receiving a second signal; a first memory cell array; a first sense amplifier connected to the first memory cell array; a first data register connected to the first sense amplifier and configured to store user data read from the first memory cell array; and a control circuit configured to execute an operation targeting the first memory cell array. The first memory cell array comprises a plurality of first memory strings. The first memory strings each comprise a plurality of first memory cell transistors. In a first mode of this semiconductor memory device, a command set instructing the operation is inputted via the first pad. In a second mode of this semiconductor memory device, the command set is inputted via the second pad.Type: ApplicationFiled: November 30, 2023Publication date: March 21, 2024Applicant: KIOXIA CORPORATIONInventors: Akio SUGAHARA, Zhao LU, Takehisa KUROSAWA, Yuji NAGAI

Patent number: 9316600Abstract: An inspection method and inspection equipment for mouth section of bottle-can including: first-inspection process for eliminating the bottle-can in which existence of a low-brightness area is detected from a monochrome inspection-image which is obtained by imaging the curl portion with irradiating white light to the curl portion in an imaging area of the bottle-can which is conveyed along a main-conveyance path; and a second-inspection process for judging quality of the bottle-can while conveying the bottle-can which is eliminated by the first-inspection process along a secondary-conveyance path, by irradiating illumination lights having two colors from different directions to the curl portion in the imaging area along substantially a tangential direction of a cylindrical surface of the mouth section so as to image a color inspection-image, and distinguishing existence or not of the asperity on the curl portion from signal strengths of the light colors of the color inspection-image.Type: GrantFiled: June 4, 2012Date of Patent: April 19, 2016Assignees: Kurashiki Boseki Kabushiki Kaisha, Universal Can CorporationInventors: Akio Kurosawa, Tadayuki Sota, Tadafumi Hirano
