Abstract: A memory device includes an input/output (I/O) interface, a secure logic for receiving a storage verifying command including an expected value of secure data via the I/O interface, an I/O logic for receiving an input request for inputting user data into the memory device and/or an output request for outputting user data therefrom and perform one of the input request and/or the output request, and a memory unit including a secure area, accessible by the secure logic, for storing the secure data and a normal area, accessible by the I/O logic, for storing the user data. The secure logic reads the secure data from the secure area in response to the input of the storage verifying command and outputs a storage verifying result to the external device, without outputting the secure data to the external device, according to whether the secure data expected value is identical with the secure data.
