Samsung is speeding up the operation of its embedded flash in mobile devices by adding its own file system between the mobile device O/S and the flash memory.

Its software is added to Windows Mobile (CE), Symbian, Linux and the RTOS operating systems in intelligent mobile devices using its OneNAND, Flex-OneNAND and MoviNAND embedded flash memory, to optimise O/S data transactions with the flash memory chips. The aim is to boot faster, download data faster and search more quickly.

Samsung has created several file systems and flash memory drivers. The mobile smart device O/S application issues file system commands, such as create, delete, read and write - which are received by Samsung's own file system software: UniFS; PocketFS; and RFS. This software then reissues the commands to flash memory drivers: UniStore; PocketStore; XSR; aor FSR, which execute them by directing the flash memory to erase data, read, write, etc. They also carry out bad block replacement and wear-levelling.

Such an approach could perhaps be taken with Windows Vista, Linux and other server operating systems to improve the way they use flash memory solid state drives.
