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 14), it is completely transparent to the
application.
