Abstract:

3D-Stacked IC (3D-SIC) based on Through-Silicon-Vias (TSV) is an emerging technology that enables heterogeneous integration and high bandwidth low latency interconnection. In this paper we propose a 3D novel cache architecture that leverages a wide TSV-based data link distributed on the entire memory array to support two orthogonal interfaces: (i) a vertical one, with a large data width, and, (ii) a side one, with a lower data width, but with more bank-type access ports, which reduces the bank conflict probability. Our simulations indicate that our proposal substantially outperforms planar counterparts in terms of access time, energy, and footprint while providing high bandwidth, low bank conflict rate, and an enriched access mechanism set.
