Patent number: 11942145Abstract: The present disclosure describes a method for memory cell placement. The method can include placing a memory cell region in a layout area and placing a well pick-up region and a first power supply routing region along a first side of the memory cell region. The method also includes placing a second power supply routing region and a bitline jumper routing region along a second side of the memory cell region, where the second side is on an opposite side to that of the first side. The method further includes placing a device region along the second side of the memory cell region, where the bitline jumper routing region is between the second power supply routing region and the device region.Type: GrantFiled: May 6, 2022Date of Patent: March 26, 2024Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Chih-Chuan Yang, Jui-Wen Chang, Feng-Ming Chang, Kian-Long Lim, Kuo-Hsiu Hsu, Lien Jung Hung, Ping-Wei Wang

Patent number: 8737074Abstract: A modular direct-current power conversion system is applied to receive a DC input voltage and output a DC output voltage. The modular direct-current power conversion system includes a main board and a plurality of DC power conversion modules. The main board includes a primary surface, a voltage input terminal, a voltage output terminal, a plurality of insertion regions, and a plurality of pin holders. When the DC power conversion module is inserted on the main board, the DC input voltage is inputted via the voltage input terminal to the DC power conversion module. The DC power conversion module converts the DC input voltage into a DC output voltage, and the DC output voltage is outputted via the voltage output terminal.Type: GrantFiled: September 13, 2011Date of Patent: May 27, 2014Assignee: Delta Electronics, Inc.Inventors: Ping-Long Yang, Chia-Hsiang Li

Patent number: 8723364Abstract: An uninterruptible power supply includes an AC-to-DC converting circuit, an energy storage unit, a first path-switching circuit, a second path-switching circuit, an integrated charge/discharge circuit and an operating control unit. If the input voltage is abnormal, the input terminal and the output terminal of the integrated charge/discharge circuit are respectively connected to the energy storage unit and the power supply output terminal, so that electric energy stored in the energy storage unit is transmitted to the power supply output terminal through the integrated charge/discharge circuit. Whereas, if the input voltage is normal, the input terminal and the output terminal of the integrated charge/discharge circuit are respectively connected to the power supply output terminal and the energy storage unit, so that the energy storage unit is charged by the integrated charge/discharge circuit.Type: GrantFiled: December 22, 2010Date of Patent: May 13, 2014Assignee: Delta Electronics, Inc.Inventors: Ping-Long Yang, Chia-Hsiang Li
