Abstract: This paper proposes Privacy-aware Data-Lifetime Control NAND Flash System (PDLCS), which changes the data-lifetime flexibly for the right to be forgotten. This system realizes both short and long term data-lifetime by In-3D Vertical Cell Processing. Furthermore, data-lifetime can be extended or shortened at any time. This system secures privacy data and thus is a universal solution for future secure storage, which is not resolved by software techniques.
