ABSTRACT:
A control device for a motor vehicle includes a central processing unit that is coupled to a non-volatile memory, a volatile memory and a key switch. The control device ensures transmission of data between memories with high reliability when control operation is repeatedly stopped and started upon the turn-off and turn-on of the key switch, while assuring a reduced period of time during which power is supplied from a back-up power supply to the device, and with a reduced frequency of writing of the data.
