Throttling memory in a computer system

摘要

Systems and methods of managing memory devices provide for reduced power consumption and better thermal management through enhanced memory throttling. In one embodiment a memory unit includes a memory device and a temperature measurement module coupled to the memory device. The temperature measurement device measures the internal temperature of the memory device. Memory throttling can therefore be implemented based on more accurate measurements and with a much shorter response time.

1. An apparatus, comprising:
a module having temperature measurement circuitry to measure a temperature of a memory unit having one or more memory devices, said measuring to be done using a thermal diode and said temperature measurement module including serial presence detect (SPD) circuitry to communicate temperature value information derived from the thermal diode to a controller, wherein the thermal diode provides temperature measurement via a difference between a first measurement signal injected into the thermal diode and a second measurement signal injected into the thermal diode and wherein the thermal diode is embedded within the one or more memory devices.
