Patent number: 9659603Abstract: A power management circuit for an electronic device sequentially activates and/or deactivates electronic circuits of the electronic device. The power management circuit provides a first group of one or more circuit power management signals to activate and/or deactivate a first electronic circuit from among the electronic circuits. Thereafter, the power management circuit provides a corresponding power management signal from among a second group of the one or more circuit power management signals that corresponds to a portion of the first electronic circuit that has been activated and/or deactivated by the first group of the one or more circuit power management signals to activate and/or deactivate a portion of a second electronic circuit from among the electronic circuits. The power management circuit continues to sequentially provide each of the one or more circuit power management signals in a similar manner until the electronic circuits of the electronic device have been activated and/or deactivated.Type: GrantFiled: December 28, 2015Date of Patent: May 23, 2017Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Hektor Huang, Yangsyu Lin, Yu-Hao Hsu, Chia-En Huang, Chiting Cheng, Chen-Lin Yang, Jung-Ping Yang, Cheng Hung Lee

Patent number: 9390816Abstract: An integrated circuit has a first circuit portion on a first level and a second circuit portion on a second level different from the first level. The first circuit portion includes a first cell having a first voltage value at a first node and a second voltage value at a second node. The second circuit portion includes a second cell coupled with the first cell, the second cell being selectively controllable to supply a voltage to the first cell based on an instruction to supply the voltage. The instruction to supply the voltage is based on a determined mismatch between the first voltage value and the second voltage value being greater than a predetermined threshold value.Type: GrantFiled: December 28, 2015Date of Patent: July 12, 2016Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Yu-Hao Hsu, Chia-En Huang, Hektor Huang, Yi-Ching Chang, Chen-Lin Yang, Jung-Ping Yang, Cheng Hung Lee

Patent number: 9240233Abstract: An integrated circuit comprises a first circuit portion comprising a plurality of first cells, each first cell comprising a first transistor having a first voltage value at a first node, and a second transistor having a second voltage value at a second node. A second circuit portion comprises a plurality of second cells. The second cells are individually coupled with a corresponding first cell of the plurality of first cells. The second cells are selectively controllable to supply a voltage to one or more of the first cells based on an instruction to supply the voltage. The instruction to supply the voltage is based on a determined mismatch between the first voltage value and the second voltage value being greater than a predetermined threshold value.Type: GrantFiled: November 12, 2014Date of Patent: January 19, 2016Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Yu-Hao Hsu, Chia-En Huang, Hektor Huang, Yi-Ching Chang, Chen-Lin Yang, Jung-Ping Yang, Cheng Hung Lee
