Abstract
Embodiments of the invention are generally directed to systems, methods, and apparatuses for thermal management using an on-die thermal sensor. In some embodiments, an integrated circuit (e.g., a memory controller) includes temperature collection logic and control logic. The temperature collection logic receives and stores temperature data from a plurality of remote memory devices each having an on-die thermal sensor. In some embodiments, the control logic controls a thermal throttle based, at least in part, on the temperature data. Other embodiments are described and claimed.
Claims21
A memory controller comprising:
- temperature collection logic to receive and store temperature data from a plurality of remote memory devices, each memory device including an on-die thermal sensor;
- and
- control logic coupled with the temperature collection logic, the control logic to provide a thermal control mechanism based, at least in part, on the temperature data, wherein the thermal control mechanism provides a proportional closed-loop feedback control response.
The memory controller of clam 1, wherein the temperature collection logic further comprises:
- one or more temperature collection control registers to store control information for the temperature collection logic.
6-10. (canceled)
A method comprising:
- collecting, at a memory controller, temperature data from a plurality of remote memory devices, each memory device including an on-die thermal sensor;
- storing, in the memory controller, processed temperature data, the processed temperature data based, at least in part, on the temperature data from the plurality of remote memory devices;
- comparing the processed temperature data to a thermal threshold value;
- and
- initiating a thermal control mechanism, if the processed temperature data exceeds the threshold value, wherein the thermal control mechanism provides a proportional closed-loop feedback control response.
(canceled)
A system comprising:
- a memory module including a plurality of memory devices, each of the plurality of memory devices having an on-die thermal sensor;
- and
- an integrated circuit coupled with the memory module through a memory interconnect, the memory controller including
- temperature collection logic to receive and store temperature data from the plurality of memory devices, and
- control logic coupled with the temperature collection logic, the control logic to control a thermal throttle based, at least in part, on the temperature data, wherein the control logic provides a proportional closed-loop feedback control response.
