Patent number: 11782466Abstract: To dynamically manage a temperature of an electronic device, a local temperature is provided by measuring a temperature of a local spot in the electronic device and a reference temperature is provided by measuring a temperature of a reference spot in the electronic device where the reference spot and the local spot are thermally coupled. A target temperature corresponding to a limit value of the reference temperature is adjusted based on the local temperature and a power level of the electronic device is controlled based on the same target temperature. The target temperature may be set to a relatively high value to secure performance of the electronic device when the local temperature is relatively low. Alternatively, the target temperature may be set to a relatively low value to pursue stability of the electronic device when the local temperature is relatively high.Type: GrantFiled: September 10, 2021Date of Patent: October 10, 2023Inventors: Yun-Hyeok Im, Myung-Kyoon Yim, Wook Kim, Kyoung-Min Lee, Kyung-Soo Lee

Patent number: 6560679Abstract: A digital data processing system is provided which includes a digital data processor, a cache memory having a tag RAM and a data RAM, and a controller for controlling accesses to the cache memory. The controller stores state information on access type, operation mode and cache hit/miss associated with the most recent access to the tag RAM, and controls a current access to the tag RAM just after the preceding access based on the state information and a portion of a set field of a main memory address for the second access. The controller determines whether the current access is applied to the same cache line that was accessed in the first access based on the state information and a portion of a set field of the main memory address for the second access, and allows the current access to be skipped when the current access is applied to the same cache line that was accessed in the preceding access.Type: GrantFiled: December 20, 2000Date of Patent: May 6, 2003Assignee: Samsung Electronics Co., Ltd.Inventors: Hoon Choi, Myung-Kyoon Yim
