Data Quality Management for Flash Memory Based Read Intensive Embedded and Multimedia Applications

Abstract

Flash memory becomes ideal storage media for small size embedded applications as well as large size multimedia applications because of its attractive characteristics like nonvolatility, small size, fast access speed, shock resistance, high reliability and further more it's rapidly increasing capacity. Embedded and multimedia applications have characteristics of write once and read many. Frequent reads degrade the quality of data, and results in data noise due to flash limited read cycles allowed. Therefore, in this paper, we effectively address the flash read limit issues and propose a novel approach to maintain the data quality within storage medium. We offer high performance and long term data quality for reliable data storage for read intensive embedded and multimedia applications.
