Hybrid memory cube new DRAM architecture increases density and performance

Multi-core processor performance is limited by memory system bandwidth. The Hybrid Memory Cube is a three-dimensional DRAM architecture that improves latency, bandwidth, power and density. Through-silicon vias (TSVs), 3D packaging and advanced CMOS performance enable a new approach to memory system architecture. Heterogeneous die are stacked with significantly more connections, thereby reducing the distance signals travel.
