Abstract
Systems and methods for determining memory module power requirements in a memory system. Embodiments include a memory system with a physical memory and a memory controller. The physical memory includes a plurality of memory devices. The memory controller is in communication with the physical memory and has a logical memory for storing power usage characteristics associated with the physical memory. The power usage characteristics are generated in response to a current operating environment of the memory system.

22. A method for measuring power utilization in a memory system, the method comprising:
-
initializing a physical memory to a minimum power operational state; measuring supplied power to the physical memory to establish nominal power consumption; generating memory access requests at a specific level of utilization targeting selected segments in the physical memory and simultaneously measuring the supplied power to the physical memory to establish power consumption for the memory access requests at the selected segments in the physical memory; computing the additional power consumption created by the memory access requests by subtracting the nominal power consumption from the power consumption for the memory access request; and storing the calculated additional power consumption as a power usage characteristic associated with the specific level of utilization and the selected segments. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
