Comment
25.CONCERNING THE SECURITY OF DATA
There is always the possibility that a soft-error (this malfunction is not permanent hence it is called soft and
the data can be restored by rewriting) may occur with semiconductor products.
When keeping the important data within an IC card, remember to give due consideration to safety when
making your circuit designs, with appropriate measures such as
(1) Keeping multiple copies of the data.
(2) Addition of ECC or CRC by software or hardware.
