CIRCUIT ARRANGEMENT WITH NON-VOLATILE MEMORY MODULE AND METHOD OF EN-/DECRYPTING DATA IN THE NON-VOLATILE MEMORY MODULE

摘要

An apparatus and method is provided for protecting data in a non-volatile memory by using an encryption and decryption that encrypts and decrypts the address and the data stored in the non-volatile memory using a code read only memory that stores encryption and decryption keys that are addressed by a related central processing unit at the same time data is being written or read from the non-volatile memory by the central processing unit.
