A first offset is calculated by determining the difference between the first known temperature and the first temperature reading. The first offset is recorded in a storage unit for later use during operation of the IC. During operation, the first offset may be added to temperature readings obtained from a temperature sensing unit to produce an adjusted temperature value. The adjusted temperature value may be compared to one or more temperature thresholds. Based on the comparisons, a power management unit may perform power control actions.Type: GrantFiled: September 26, 2011Date of Patent: March 3, 2015Assignee: Apple Inc.Inventors: Toshinari Takayanagi, Jung Wook Cho

Patent number: 8963566Abstract: An integrated circuit device includes component devices (that include primary and alternate devices) and storage elements connected to the component devices. The storage elements store different sets of repair addresses indicating which of the primary devices and alternate devices are to be enabled. Further, a controller is connected to the storage elements, and a temperature sensor is connected to the controller. The temperature sensor senses the temperature. The controller selects one of the different storage elements to select at least one of the sets of repair addresses based on the temperature sensed by the temperature sensor. The sets of repair addresses share use of at least one of the alternate devices and at least one of the primary devices.Type: GrantFiled: October 5, 2012Date of Patent: February 24, 2015Assignee: Intenational Business Machines CorporationInventors: John R. Goss, Robert McMahon, Troy J. Perry
