Reducing power consumption by using a different memory chip for background processing
Power consumption can be reduced by using a different memory chip for background processing. For example, a computing device can determine that a first application executing on a device complies with an application programming interface (API) for using a smaller dynamic access memory (DRAM) chip of the device that is smaller and consumes less power than a main DRAM chip of the device. The computing device can determine the device is inactive. The computing device can perform, by the API, background processing for the first application using the memory chip.
