Write-Aware Replacement Policies for PCM-Based Systems
The gap between processor and memory speeds is one of the greatest challenges that current designers face in order to develop more powerful computer systems. In addition, the scalability of the Dynamic Random Access Memory (DRAM) technology is very limited nowadays, leading to consider new memory technologies as candidates for the replacement of conventional DRAM. Phase-Change Memory (PCM) is c...
متن کاملMemory Management Techniques for Large-Scale Persistent-Main-Memory Systems
Storage Class Memory (SCM) is a novel class of memory technologies that promise to revolutionize database architectures. SCM is byte-addressable and exhibits latencies similar to those of DRAM, while being non-volatile. Hence, SCM could replace both main memory and storage, enabling a novel single-level database architecture without the traditional I/O bottleneck. Fail-safe persistent SCM alloc...
متن کاملDRAM-Aware Last-Level Cache Writeback: Reducing Write-Caused Interference in Memory Systems
Read and write requests from a processor contend for the main memory data bus. System performance depends heavily on when read requests are serviced since they are required for an application’s forward progress whereas writes do not need to be performed immediately. However, writes eventually have to be written to memory because the storage required to buffer them on-chip is limited. In modern ...
متن کاملWear-Aware Algorithms for PCM-Based Database Buffer Pools
PCM can be used to overcome the capacity limit and energy issues of conventional DRAM-based main memory. This paper explores how the database buffer manager can deal with the write endurance problem, which is unique to PCM-based buffer pools and not considered by conventional buffer algorithms. We introduce a range of novel buffer algorithms addressing this problem, called wear-aware buffer alg...
متن کاملA Study on the Challenges and Prospects of PCM Based Main Memory Architectures
For several decades, computer’s memory has been volatile. High speed memories such as DRAM and SRAM have been used as main memory and cache memory respectively. Magnetic disks are used as the persistent secondary storage devices. The present DRAM based main memory has reached its energy limits. Due to the advent of nonvolatile memories like PCM, MRAM, RRAM, FeRAM and Flash, there is growing int...
