Abstract
A processor monitors, directly or indirectly, the amount of time it takes for the memory controller to respond to one or more memory access requests. When this memory access latency indicates that a memory latency tolerance of a program thread has been exceeded, the processor can apportion additional power to the memory controller, thereby increasing the speed with which the memory controller can process memory access requests.
