Data Placement Through Clustering Sequential Writes and Isolating Cold Pages for Write Amplification Reduction in NAND Flash Memory
NAND flash-based solid-state drives have revolutionized storage solutions in resource-restrictive electronics owing to their compact size, low power consumption, and high shock resistance. However, they face limitations such as asymmetrical read, write, and erase operations, leading to write amplification (WA), decreased performance, and shorter lifespan. This paper introduces clustering sequential writes and cold isolation (CSWCI), a novel data placement scheme that addresses two critical challenges: identifying sequential writes hidden within random input/output streams and efficiently migrating cold pages. CSWCI employs logical address-based clustering to detect sequential patterns, enhancing spatial locality and reducing random writes. Additionally, it accurately isolates frozen pages that have not been used recently and are not expected to be used again during garbage collection, thus minimizing unnecessary migrations and WA. Unlike conventional methods, CSWCI optimizes memory usage, aligning with the low power consumption requirement of mobile devices such as smartphone and tablet PC. Experimental results demonstrate a maximum 33% reduction in valid page copies, which typically worsens WA compared to existing schemes, indicating improved performance and durability.

期刊介绍:
IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest.
IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on:
Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals.
Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering.
Development of new or improved fabrication or manufacturing techniques.
Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
