Performance Improvement of Flash Memory By Error Pre-checking Scheme and Error Correction

Flash memory serves as a pivotal nonvolatile data storage technology, ensuring data persistence even in the absence of power, and is ubiquitous in devices such as USB drives, SSDs, and memory cards. The reliability of this technology is paramount for safeguarding valuable data. Establishing robust error check systems, adhering to stringent data integrity policies, and meticulously preventing data corruption during write operations are imperative practices to maintain data integrity. Employing pre-error checking procedures can bolster control over error data, thus diminishing erroneous decisions. Introducing a Dynamic Error Pre-Check Strategy (DEPS) offers a proactive approach to detecting and mitigating data imperfections in Flash memory, thereby enhancing its reliability and performance. Furthermore, enhancing SSD readability can be accomplished by partitioning large files into smaller pages, a strategy that not only enhances SSD readability but also augments average reading speed, optimizes space utilization, and curtails energy consumption in flash memory systems. This optimized approach results in notable reductions in area, on-chip power, junction temperature, and process delay by 60.19%, 65.86%, 51.7%, and 66.5% respectively. These reductions signify improved resource efficiency, decreased power consumption, improved thermal management, and, ultimately, increased reliability and performance of Flash memory systems.
