摘要： An exemplary computing device includes a plurality of circuits and/or a plurality of in-situ monitors configured to generate outputs that indicate one or more operating conditions of the circuits. The computing device also includes a system management unit configured to detect a potentially faulty voltage-to-frequency ratio implemented by one of the circuits based at least in part on one or more of the outputs. The system management unit is also configured to modify the potentially faulty voltage-to-frequency ratio based at least in part on one or more of the outputs. Various other devices, systems, and methods are also disclosed.

摘要： Dynamic memory operations are described. In accordance with the described techniques, a system includes a stacked memory and one or more memory monitors configured to monitor conditions of the stacked memory. A system manager is configured to receive the monitored conditions of the stacked memory from the one or more memory monitors, and dynamically adjust operation of the stacked memory based on the monitored conditions. In one or more implementations, a system includes a memory and at least one register configured to store a ranking for each of a plurality of portions of the memory. Each respective ranking is determined based on an associated retention time of the respective portion of the memory. A memory controller is configured to dynamically refresh the portions of the memory at different times based on the ranking for each of the plurality of portions of the memory stored in the at least one register.
