Abstract
Provided is a method of operating a semiconductor device. A method of operating a semiconductor device includes storing secure data in a secure area of a memory in response to detecting a system failure; encrypting the secure data stored in the secure area by using a random key to generate encrypted secure data; storing the encrypted secure data in the secure area; and dumping the secure area and a non-secure area of the memory.
