Abstract
A system includes one or more memory circuits and one or more sensor circuits that are separate from the memory circuits. A temperature estimation circuit estimates a temperature of the memory circuits based on sensor measurements from the sensor circuits and based on an empirically-derived relationship between the temperature and the sensor measurements. The temperature estimate is finer in granularity than a temperature indication provided by the memory circuits. For example, a given temperature indication value covers a range of 5 degrees Celsius, while the temperature estimate may be any integer temperature value or a decimal temperature value (e.g., to tenths or hundredths of degrees C.). A power control circuit in the system uses the temperature estimate to control a rate at which one or more agent circuits in the system generate memory requests to the memory circuit, which may control the temperature of the memory circuits.
