Electrically erasable programmable-ROM operating method for use in e.g. motor vehicle control device, involves storing data either with value or with reference to standard value based on comparison result
The method involves determining a standard value and comparing the standard value with a value of a data (102), which is provided in a flash memory device (100). The data is stored either with the value or with a reference to the standard value based on the comparison result. An internal area in the memory device contains information to check whether the reference is given to the standard value or to a free value. Independent claims are also included for the following: (1) a central processing unit for operating a memory device (2) a computer and/or microprocessor program with a code for operating a memory device (3) a computer and/or microprocessor program product with a code for operating a memory device.
