摘要： An integrated circuit includes a memory and peripheral circuits with a temperature sensor used to automatically adjust operating voltages. The temperature sensor includes a reference circuit that generates a first reference with a first non-zero temperature coefficient and a second reference with a second temperature coefficient having a different magnitude than the first non-zero temperature coefficient. A detector circuit on the integrated circuit, having temperature and process variation compensation, converts a difference between the first and second references into a digital signal indicating temperature on the integrated circuit.

摘要： A method for measuring temperature is used to obtain a room temperature of a room. The method for measuring temperature includes: obtaining a first temperature inside an operating area in a portable electronic device in the room; obtaining a second temperature outside the operating area in the portable electronic device by a first temperature sensor; calculating a temperature difference between the first temperature and the second temperature; obtaining a compensation temperature according to the temperature difference and a compensation temperature table; and calculating the room temperature according to the second temperature and the compensation temperature.

摘要： Embodiments of the invention are generally directed to systems, methods, and apparatuses for thermal sensor power savings using a toggle control. In some embodiments, an integrated circuit (e.g., a memory device) includes an on-die thermal sensor, a storage element (e.g., a register), and toggle logic. The toggle logic may transition the thermal sensor from a first power consumption level to a second power consumption level responsive, at least in part, to a toggle indication.

摘要： A semiconductor device that may include temperature sensing circuits is disclosed. The temperature sensing circuits may be used to control various parameters, such as internal regulated supply voltages, internal refresh frequency, or a word line low voltage. In this way, operating specifications of a semiconductor device at worst case temperatures may be met without compromising performance at normal operating temperatures. Each temperature sensing circuit may include a selectable temperature threshold value as well as a selectable temperature hysteresis value. In this way, temperature performance characteristics may be finely tuned. Furthermore, a method of testing the temperature sensing circuits is disclosed in which a current value may be monitored and temperature threshold values and temperature hysteresis values may be thereby determined.
