Processor and DRAM integration by TSV-based 3-D stacking for power-aware SOCs

With the rapid popularization of mobile devices, the low-power and energy-efficient became far more important than the system operating frequency. This work demonstrates a processor and DRAM integration scheme by TSV-based 3-D stacking and the performance and energy efficiency is evaluated by an ESL design methodology. The integration scheme comprising Sans-Cache DRAM (SCDRAM) architecture which is designed under the power and energy considerations is explored. Experiment results show the proposed architecture can greatly reduce 80% energy while having 23.5% of system performance improvement.
