Magnetic tunnel junction temperature sensors and methods |
摘要 |
Techniques of sensing a temperature of a heat source disposed in a substrate of an integrated circuit are provided. According to one exemplary method, a Magnetic Tunnel Junction ("MTJ") temperature sensor is provided over the heat source. The MTJ temperature sensor comprises an MTJ core configured to output a current during operation thereof. The value of the current varies based on a resistance value of the particular MTJ core. The resistance value of the MTJ core varies as a function of the temperature of the heat source. A value of the current of the MTJ core can then be associated with a corresponding temperature of the heat source.
