ABSTRACT:
Through-Silicon Interposer (TSI) has been recently proposed to provide high memory bandwidth and improve energy efficiency of the main memory system. However, the impact of TSI on the main memory system architecture has not been well explored. While TSI improves the I/O energy efficiency, we show that it results in an unbalanced memory system design in terms of energy efficiency as the core DRAM dominates overall energy consumption. To balance and improve the energy efficiency of a TSI-based memory system, we propose microbank, a novel DRAM device organization in which each bank is partitioned into multiple smaller banks (called microbanks) that operate independently like conventional banks with minimal area overhead. The microbank organization significantly increases the amount of bank-level parallelism to improve performance while increasing energy efficiency of TSI-based memory system. The massive number of microbanks also simplifies the memory system design with the larger number of open DRAM rows.
