Information handling system including a memory device capable of being powered by a battery

An information handling system (IHS) includes a processor, a memory module coupled to the processor, a memory device, and a power source, coupled to the memory device, for supplying power to the memory device. Also, the IHS includes a first battery, coupled to the memory device, for supplying power to the memory device, a second battery, located on the memory module and coupled to the memory device, for supplying power to the memory device, and a switching circuit coupled to the memory device, the power source, the first battery, and the second battery. The switching circuit is for, in response to determining that the power source is unavailable to supply power to the memory device, supplying power from the first battery. The switching circuit is also for, in response to determining that the power source and the first battery are unavailable to supply power to the memory device, supplying power from the second battery.
