Abstract

Methods, systems, and apparatuses relating to package on package memory refresh and self-refresh rate management are described. In one embodiment, an apparatus includes a processor die, a dynamic memory die mounted to and overlapping the processor die, a first thermal sensor of the processor die disposed adjacent to a first hot spot from a first type of workload and a second thermal sensor of the processor die disposed adjacent to a second hot spot from a second type of workload, and a hardware control circuit of the processor die to cause a refresh of a capacitor of the dynamic memory die when either of an output of the first thermal sensor exceeds a first threshold value and an output of the second thermal sensor exceeds a second threshold value.
