An information handling system includes a first non-volatile memory, a central processing unit, and a basic input/output system (BIOS). The first non-volatile memory is divided into a plurality of namespaces including a first namespace and a second namespace. The central processing unit writes data to the first non-volatile memory by namespace of the non-volatile memory. The BIOS includes a key table. The key table stores a first key for the first non-volatile memory, a second key for the first namespace, and a third key for the second namespace. The second key is utilized to securely erase the first namespace without erasing the second namespace.
