In recent years, energy dissipation in mission-critical computers has emerged as a significant challenge, prompting the exploration of innovative solutions. One promising approach is the development of non-volatile memory-based hybrid main memory architectures, which integrate different types of memory to enhance performance and efficiency. In this paper, we present a comprehensive examination of a new memory management scheme designed specifically for a hybrid memory system that combines Dynamic Random-Access Memory (DRAM) with Persistent Random-Access Memory (PRAM) and leverages flash memory for storage. The primary objective of our proposed scheme is to reduce the frequency of write operations on PRAM, which can contribute to memory wear, and to minimize the number of erase operations on flash memory, which can limit its lifespan. To assess the effectiveness of our memory management approach, we conducted a series of evaluations comparing it with traditional legacy memory management schemes. This comparison was performed through trace-driven simulations, allowing us to analyze various performance metrics and energy consumption patterns. Our findings aim to demonstrate the advantages of our proposed scheme in optimizing memory usage and enhancing the overall efficiency of memory systems in mission-critical applications.
