Abstract
A memory module of an electrical apparatus has a normal firmware section. A method for determining correctness of program code in the memory module includes making a value stored in at least one specific address match a first rule; providing a inspection instruction; and determining whether the value stored in at least one specific address matches the first rule or not according to the inspection instruction. The electrical apparatus executes the inspection instruction at power-on in order to determine correctness of the program code in the normal firmware section.
