A Study on Reconstructing Memory Hierarchy that Utilizes Emerging Devices

处理器性能仍在不断提高，以实现日益增长的性能需求。然而，计算机系统不能为我们提供足够的性能来满足需求。这是由于内存系统的性能不佳。此外，内存消耗巨大的功率。考虑到以上，我们开始了我们的项目。我们假设我们可以使用下一代存储设备，如STT-MRAM。在这种假设下，我们尝试重构内存层次结构，以实现高性能、低功耗和可靠的存储系统。该存储系统可将能量延迟积提高49%。

Processor performance is still improved in order to achieve increasing performance demand. However, computer system can not provide us with enough performance to meet the demand. This is due to the poor performance of memory system. In addition, memory consumes huge power. Considering the above, we started our project.We assume that we can use next-generation memory devices such as STT-MRAM. Under this assumption, we try to reconstruct memory hierarchy in order to achieve high-performance, low-power, and dependable memory system.The proposed memory system can improve energy-delay product by up to 49%.
