Abstract

This paper presents on-line algorithm that determines further datapath for incoming requests - should they temporarily stay in RAM buffers for future merge operation or should they be written to disks immediately. With workload analysis in real time, the delay time spent in RAM buffer is a self-tuned parameter. This approach increases sequential write requests latency but sufficiently raises the overall performance of sequential write workloads without the use of expensive non-volatile cache.

Write performance improvement by hiding R drift latency in phase-change RAM
DAC '12: Proceedings of the 49th Annual Design Automation Conference

Phase-change RAM (PRAM) is considered to be one of the most promising candidates to complement or replace DRAM in the near future. However, it is imperative to overcome the limitations of PRAM, especially, long write latency for its widespread ...
Dual region write buffering: making large-scale nonvolatile buffer using small capacitor in SSD
SAC '15: Proceedings of the 30th Annual ACM Symposium on Applied Computing

Write buffering not only enables Solid State Drive (SSD) to immediately respond to the write request but also increases the lifespan of the SSD by reducing the amount of data written to the flash memory. However, since the DRAM which is used as a write ...
Write reconstruction for write throughput improvement on MLC PCM based main memory

The emerging Phase Change Memory (PCM) is considered as one of the most promising candidates to replace DRAM as main memory due to its better scalability and non-volatility. With multi-bit storage capability, Multiple-Level-Cell (MLC) PCM outperforms ...
