Main memory plays a critical role in a computer system's performance and energy efficiency. Three key parameters define a main memory system's efficiency: latency, bandwidth, and power. Current memory systems tries to balance all these three parameters to achieve reasonable efficiency for most programs. However, in a multi-core system, applications with various memory demands are simultaneously executed. This paper proposes a heterogeneous main memory with three different memory modules, where each module is heavily optimized for one the three parameters at the cost of compromising the other two.
