![]() Today NandFlash Memory(hence fort simply referred to as Flash) is used in handhold electronic devices like mobile, cameras, iPODS, music players, PDAS due to it's characteristics light weight, low power consumption, shock resistant and faster access. We conduct a series of trace-driven simulations and experimental results show that our proposed FAPRA algorithm outperforms the state-of-the-art algorithms in terms of page hit ratio, the number of write operations, runtime, and the degree of wear leveling. Since the dirty victim page often contains clean data that exist in both the main memory and the NAND flash memory based storage device, FAPRA only writes the dirty data within the victim page back to the NAND flash memory based storage device in order to reduce the redundant write operations. FAPRA introduces an efficient victim page selection scheme taking into account the benefit-to-cost ratio for evicting each victim page candidate and the combined recency and frequency value, as well as the erase count of the block to which each page belongs. Therefore, this paper review past performance of mapping strategies limitation and consider other way to improve duplication process such as focusing more on data size reduction and how data is arranged and transferred during data duplication process across flash devices.ĭue to the limited main memory resource of consumer electronics equipped with NAND flash memory as storage device, an efficient page replacement algorithm called FAPRA is proposed for NAND flash memory in the light of its inherent characteristics. Unfortunately, to duplicate a 64GB (eMMC) memory typically takes up between two to seven hours plus speed specification provided by vendors for the duplicators performance is much lower when tested in real experience. In order to store a bulk of data in a shorter time, duplicator machine is used to speed up the transfer and duplication process where generally duplication process is done by copying each data bit from the master device to the targeted device including the unused memory region. ![]() It is suitable for high-performance applications and can be used as a replacement for traditional storage media, such as hard disk drive (HDDs). One of the examples of widely used flash memory for embedded technology is Embedded Multimedia Card (eMMC). Flash memory has recently been widely adopted in embedded applications as it has several strong points, including its non-volatility, fast access speed, shock resistance, and low power consumption. ![]()
