Abstract

Flash is widely used as a storage medium of mobile devices such as MP3 players, cellular phones and digital cameras due to its tiny size, low power consumption and shock resistant characteristics. Currently, there are many studies to replace HDD with flash because of its numerous strong points. To use flash as a storage medium, FTL(Flash Translation Layer) is required since flash has erase-before-write constraints and sizes of read/write unit and erase unit are different from each other. Recently, new type of flash called block flash memory is introduced. The large block flash has different physical structure and characteristics from previous flash memory. So existing FTLs are not efficiently operated on large block flash memory. In this paper, we propose an efficient FTL for large block flash based on FAST(Fully Associative Sector Translation) scheme and page-level mapping on data blocks.
