Abstract:
Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of controlling a memory of a computing device by an adaptive memory controller. The method includes collecting usage data from the computing device over a first bin, wherein the first bin is associated with a first weight, wherein the first weight is indicative of one or more of a first partial array self-refresh (PASR) setting a first partial array auto refresh (PAAR) setting and a first deep power down (DPD) setting. The method further includes associating the collected data with a second weight, adapting the first bin based on the second weight, wherein the second weight is indicative of one or more of a second PASR, PAAR, and DPD setting. The method further includes controlling the memory during the next first bin based on the second weight.
