Samsung Crafts Linux File System For NAND Flash

The software allows NAND flash memory to store code as well as data.

SAN JOSE, Calif. — Electronics giant Samsung Electronics Co. Ltd. has created a file system for the Linux operating system called Robust File System, which can be stored and operate from NAND flash, Samsung said Tuesday (June 22).

Samsung's Linux software allows the NAND flash memory to store code as well as data and, as a result, it should be possible to eliminate NOR flash memory from mobile telephone handsets.

By eliminating the need for NOR flash memory and supporting the Linux operating system with a demand-paging function, Samsung said it could lower overall costs and reduce space requirements in mobile handhelds, the company said.

The Robust File System also offers greater data preservation capabilities in case of power disruption and takes care of "wear-leveling," which takes into account the limited endurance capability of flash memory and prevents particular memory cells being used repeatedly.

To address the problem of data loss from corrupted file allocation tables (FAT), the software supports the use of a transactional FAT for external memory cards.
