Error Handling
MultiMediaCards are defined as error free devices or as devices with a defined maximum bit error rate
(with external error correction circuitry). To correct defects in the memory field of the cards the system
may include error correction codes in the payload data (ECC). This correction is intended to correct static
errors. Additionally two methods of detecting errors generated during the data transfer (dynamic errors)
via a cyclic redundancy check (CRC) are implemented.
On Card Error Correction Code (ECC)
These Renesas MultiMediaCards is free of static errors. All errors are covered inside the card, even errors
occurring during the lifetime of these Renesas MultiMediaCards are covered for the user. The only effect
which may be notified by the end user is, that the overall memory capacity may be reduced by small
number of blocks. All flash handling is done on card, so that no external error correction is needed.
