Memory operations using system thermal sensor data

摘要

Memory operations using system thermal sensor data. An embodiment of a memory device includes a memory stack including one or more coupled memory elements, and a logic chip coupled with the memory stack, the logic chip including a memory controller and one or more thermal sensors, where the one or more thermal sensors include a first thermal sensor located in a first area of the logic chip. The memory controller obtains thermal values of the one or more thermal sensors, where the logic element is to estimate thermal conditions for the memory stack using the thermal values, the determination of the estimated thermal conditions for the memory stack being based at least in part on a location of the first thermal sensor in the first area of the logic element. A refresh rate for one or more portions of the memory stack is modified based at least in part on the estimated thermal conditions for the memory stack.
