Abstract
The speed of computing processor has been improved dramatically with multi-core architecture. However, the overall computer system performance shows slow improvement because of the sluggish speed of storage system. Several researches have been done to improve the performance of storage system by introducing Solid-State Disk technology with NAND Flash memory. In this paper, we propose new hybrid Solid-State Disk (SSD) architecture to combine Phase-change Memory (PRAM) and NAND Flash memory to achieve high-performance. Our experimental results show that the proposed scheme shows up to 140% performance improvement without endurance problem in PRAM in write-intensive workloads, compared to SSD with only NAND Flash memory.
