To prevent data from being lost or corrupted, TrueFFS uses the following mechanisms:
•
•
4.5
TrueFFS implements a unique MLC-tailored Error Correction Code (ECC) algorithm to ensure data
reliability. The advanced algorithm provides 4-bit Error Detection Code/Error Correction Code
(EDC/ECC), based on a patented combination of BCH and Hamming code algorithms.

When writing, copying, or erasing the flash device, the data format remains valid at all
intermediate stages. Previous data is never erased until the operation has been completed and
the new data has been verified.
A data sector cannot exist in a partially written state. The operation is either successfully
completed, in which case the new sector contents are valid, or the operation has not yet been
completed or has failed, in which case the old sector contents remain valid.
