  • Patent number: 10761769
    Abstract: A memory sub-system is disclosed that makes accessible accumulated memory temperature statistics in relation to a target memory portion. This can be accomplished by maintaining one or more hold variables and one or more accumulation variables. The accumulation variables can be iteratively updated upon triggers such as a timer expiration or I/O event. Updating the accumulation variables can include obtaining a current temperature and tracking one or more of: a maximum, minimum, and mean temperature across the iterations. An accumulation value can track how many times the accumulation variables have been updated. When the accumulation value reaches an accumulation action threshold, the current state of the accumulation variables can be used to update the hold variables. The accumulation value and accumulation variables can then be reset and used for accumulation of additional temperature statistics.

    Abstract: The disclosed embodiments relate to methods, systems and apparatus for dynamic temperature aware functional safety. The disclosed embodiments provide adaptive techniques to track extended dynamic temperature range of a System-on-Chip (SOC) and automatically tune critical IP components of the SOC so that system can operate reliably even at high temperatures. The disclosed embodiments relax the overdesign of the SOC components by reusing existing components such as a ring oscillator to determine temperature at different regions of the SOC. In one embodiment, the disclosed principles use a Calibrated Ring Oscillator (CRO) temperature sensors. The CRO-based temperature sensors provide fast temperature measurement suitable for detecting dynamic temperature ranges and temperature rate of change. The CROs are existing on the SOC and do not require addition of additional sensors.

This sensor reference module is couplable with the first sensing resistor or second sensing resistor. A processing circuit coupled to the oscillator provides a sensor signal indicative of the frequency or period of the oscillation signal. The sensor signal has first and second values with the sensor reference module coupled with the first sensing resistor and with the second sensing resistor, respectively, the first and second values being thus jointly indicative of the physical variable sensed.

  • Patent number: 8967855
    Abstract: An electronic device that determines an external temperature is described. During operation, the electronic device uses a sensor mechanism (such as an integrated temperature sensor) to determine an internal temperature of the electronic device. Then, a thermoelectric device (which may be based on the Peltier effect and/or the Seeback effect) determines the relative temperature difference between the internal temperature and the external temperature. Next, the external temperature may be determined based on the internal temperature and the temperature difference. For example, the external temperature may be determined relative to a threshold value. Furthermore, an electrical signal (such as a voltage or a current) output by the thermoelectric device may be used to recharge a battery and, more generally, a power source in the electronic device.

  • Patent number: 8961004
    Abstract: Methods and systems to determine an internal temperature of a rechargeable lithium-ion cell based on a phase shift of the cell. Internal cell temperature may be determined with respect to an internal anode temperature and/or an internal cathode temperature. Internal anode temperature may be determined based on a phase shift of a frequency within a range of approximately 40 Hertz (Hz) to 500 Hz. Internal cathode temperature may be determined based on a phase shift of a frequency of up to approximately 30 Hz. A temperature sensor as disclosed herein may be powered by a monitored cell with relatively little impact on cell charge, may be electrically coupled to cell but housed physically separate from the cell, and/or may monitor multiple cells in a multiplex fashion. A rate of change in phase shift may be used to initiate pre-emptive action, without determining corresponding temperatures.

  • Publication number: 20150002023
    Abstract: A light-emitting diode (LED) device includes first and second LED dies with the same structure and that are both encapsulated by the same silicone layer. The first LED is supplied with sufficient drive current to illuminate the LED. Control circuitry supplies the second LED with a constant current, determines the voltage across the second LED, and calculates the temperature of the second LED based on the voltage across the second LED. The constant current has a maximum magnitude that never exceeds the maximum magnitude of the drive current. The LED device is able to calculate the temperature of a diode with a gallium-nitride layer (GaN or GaInN) that is receiving a large drive current and emitting blue light by determining the voltage across an adjacent similar diode with a gallium-nitride layer through which a small constant current is flowing. Preferably, the band gap of the LEDs exceeds two electron volts.
