Outline of Final Research Achievements

This research aims for power reduction on Through Silicon Vias (TSVs) which extend in the stacking direction between three-dimensionally mounted high-density LSI chips. For the power reduction, we proposes charge recycling transmission scheme of stacked I/O configuration. In the proposed scheme, we also show theoretical approach to clarify the power reduction ratio. The approach suggests that 32-64-bits bus width is suitable for the transmission scheme. Using the bus width, actual circuits has been designed in standard CMOS process. Simulations of the circuit shows that the power consumption is comparable to the prior art of special semiconductor process. This suggests that cutting-edge power reduction can be achieved by standard CMOS process and wide bus width. Then, test-chip has been actually prototyped using a 65 nm CMOS process.

Academic Significance and Societal Importance of the Research Achievements

IoTやディープラーニングにおいて、膨大なデータを処理するには、ハイパフォーマンスな計算ユニット、すなわち半導体LSIが必要である。このような半導体LSIの高性能化の手段として3次元実装LSIがあり、これは今後のハイパフォーマンスコンピューティング(HPC)には欠かせないものとなってくる。一方、データサーバーへの膨大な冷却電力需要で分かるように、高性能化と同時に低消費電力化を実施しないと実社会で役立てない。したがって、HPCを実社会で活用し豊かで持続的な高度情報化社会を実現するために、3次元実装LSI内のデータ通信にかかる電力を削減するとともに、その設計メソドロジを示した。
