Abstract
A method of operating a memory system includes setting a secured area in a volatile memory device of the memory system during a secure mode, writing secure data in the secured area during the secure mode, and when a write command for the secured area is inputted in a normal operation mode, preventing a write operation from occurring and generating an error signal. Accordingly, the secured area is set in the volatile memory device so that the hacking and the data forgery may be prevented.
