This book provides a comprehensive overview of key technologies being used to address challenges raised by continued device scaling and the extending gap between memory and central processing unit performance.  Authors discuss in detail what are known commonly as “More than Moore” (MtM), technologies, which add value to devices by incorporating functionalities that do not necessarily scale according to “Moore's Law”.  Coverage focuses on three key technologies needed for efficient power management and cost per performance: novel memories, 3D integration and photonic on-chip interconnect.
