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 disk, making it completely transparent to the OS. In addition, since it operates under the OS file
system layer (see Figure 10), it is completely transparent to the application.
TrueFFS technology support includes:
TrueFFS technology features:
