Methods of operating memory system

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 isset in the volatile memory device so that the hacking and the data forgery may be prevented.

Description

technical field [0001] Exemplary embodiments relate to methods of operating a memory system, and more particularly, to methods of operating a memory system including setting a secure area in a memory device. Background technique [0002] To prevent hackers from attacking memory devices, in conventional methods, firewalls can block malicious codes from external devices using authentication keys, or vaccine programs can prevent malicious codes from being installed. [0003] However, when a user directly installs a program including malicious code or unknown malicious code is installed by a method such as a spoofing text message, the memory device may not be protected from hacker attacks. Therefore, it is desirable for a memory system or memory device to be protected against user-initiated hacking. Contents of the invention [0004] Exemplary embodiments provide a method of operating a memory system including setting a secure area in a volatile memory device to prevent hacki...
