Abstract
Phase change memory (PCM) is one of the promising non-volatile memory (NVM) technologies since it provides both high capacity and low idle power consumption. However, relatively slow access latency is one of the major challenges in using PCM as main memory. Therefore, in recent researches, it is attempting to construct heterogeneous memory systems by combining such NVM with
DRAM. One of the major problems with using those systems is placing the data in the appropriate type of memory. In this paper, we propose an object placement method to address data placement problem in heterogeneous memory
systems. With context-aware object profile information, we could dynamically detect memory access patterns of objects and determine the proper memory to place the objects on. We demonstrate the effectiveness of the proposed method by simulating memory access latency and energy consumption using the four selected workloads of the SPEC benchmark.
