Abstract
A device and method for data protection by scrambling address lines is disclosed, which includes a redundancy area-setting unit, a redundancy area-mapping rule unit, an area check unit, an address-mapping unit and a multiplexer. The area check unit compares an address of address bus with addresses of first data area or redundancy area stored in the redundancy area-setting unit and accordingly generates a comparison result. The address-mapping unit converts the address of address bus into an address of redundancy area. The multiplexer outputs the address of redundancy area when the comparison result and a switch control signal are logic true; otherwise the address of address bus is output.
