T FFS T RUE ECHNOLOGY 5.1 General Description M-Systems’ patented TrueFFS technology was designed to maximize the benefits of flash memory while overcoming inherent flash limitations that would otherwise reduce its performance, reliability and lifetime. TrueFFS emulates a hard ...
Page 13
Built-In Operating System Support The TrueFFS driver is integrated into all major OSs, including: Windows CE/NT/NT Embedded/XP, Linux (various kernels), VxWorks, Nucleus, QNX, DOS, Symbian, and others. For a complete listing of all available drivers, please refer to M-Systems’ ...
Page 14
Dynamic Wear-Leveling TrueFFS uses statistical allocation to perform dynamic wear-leveling on newly written data. This not only minimizes the number of erase cycles per block, it also minimizes the total number of erase cycles. Because a block erase is the ...
Page 15
Special Features through I/O Control (IOCTL) Mechanism In addition to standard storage device functionality, the TrueFFS driver provides extended functionality. This functionality goes beyond simple data storage capabilities to include features such as: format the media, binary partition(s) access, ...
