## Abstract

In one or more embodiments, one or more systems, methods, and/or processes may determine that an information handling system is to be powered down and provide, to a non-volatile memory medium via a power coupling of the non-volatile memory medium, information indicating that the non-volatile memory medium is to be powered down. For example, the power coupling of the non-volatile storage medium may include one or more conductors, and the information indicating that the non-volatile memory medium is to be powered down may be provided via at least one of the one or more conductors. In one or more embodiments, the non-volatile memory medium may include volatile storage and non-volatile storage. For example, based at least on the information indicating that the non-volatile memory medium is to be powered down, the non-volatile memory medium may store information, that is stored by the volatile storage, via the non-volatile storage.
