Abstract

Most mobile computers use NAND flash memory-based storage devices for storing data. In flash memory-based storage devices, flash translation layer is widely used to translate logical address from a file system to physical address of flash memory by using mapping tables. The legacy FTLs have a problem that they must maintain very large mapping tables in the RAM. In general, however, most mobile computers do not have sufficient RAM. In order to address these issues, we proposed a new mapping table management scheme which can be used in NAND flash-based mobile computers. We showed through the trace-driven simulations that the proposed scheme reduces the space overhead dramatically but does not increase the time overhead.
