A method of fabricating a semiconductor memory device includes etching a substrate that forms a trench that crosses active regions of the substrate, forming a gate insulating layer on bottom and side surfaces of the trench, forming a first gate electrode on the gate insulating layer that fills a lower portion of the trench, oxidizing a top surface of the first gate electrode where a preliminary barrier layer is formed, nitrifying the preliminary barrier layer where a barrier layer is formed, and forming a second gate electrode on the barrier layer that fills an upper portion of the trench.

A television (TV) includes an audio signal processing unit which processes a audio signal, a display unit which displays an audio quality setting state, a determination unit which determines if an event for checking audio quality has occurred, and a control unit which controls the display unit to display an audio quality setting state showing improved audio quality if the event has occurred.

TV and audio processing method thereof

A digital content authentication system, an image display apparatus applied to the system, and a digital content authentication controlling method of the system are provided. The image display apparatus includes an interface section which demands authentication results from a plurality of source providing apparatuses through a bus and receiving responses to the demanding for the authentication result and an output section outputting the authentication results by the received response. Accordingly, the image display apparatus can recognize the authentication states of the source providing apparatuses.
