Abstract
A memory having a first authentication code includes a communication port configured to transmit information including debug data to or receive the information including debug data from the external device; and a debug port controller that is usable for blocking of a communication path connecting to the communication port. The debug port controller is configured to receive an authentication request including a second authentication code from an external device, determine whether the second authentication code matches the first authentication code, and block the communication path if the second authentication code is not determined to match the first authentication code. The communication port may be configured to be disabled until the second authentication code matches the first authentication code.
