In a method of a vertical memory device, insulation layers and sacrificial layers are alternately and repeatedly formed on a substrate. A hole is formed through the insulation layers and the sacrificial layers that expose a top surface of the substrate. Then, an interior portion of the hole may be enlarged. A semiconductor pattern is formed to partially fill the enlarged portion of the hole. A blocking layer, a charge storage layer and a tunnel insulation layer may be formed on a sidewall of the hole and the semiconductor pattern. Then, the tunnel insulation layer, the charge storage layer and the blocking layer are partially removed to expose a top surface of the semiconductor pattern. A channel is formed on the exposed top surface of the semiconductor pattern and the tunnel insulation layer. The sacrificial layers are replaced with gate electrodes.

A test interface device includes a serializer, an optical transmitter, an optical receiver, and a deserializer. The serializer receives parallel test signals from automatic test equipment, and serializes the parallel test signals into a serial test signal. The optical transmitter converts the serial test signal into an optical test signal. The optical receiver receives the optical test signal from the optical transmitter, and converts the optical test signal into the serial test signal. The deserializer deserializes the serial test signal into the parallel test signals, and transmits the parallel test signals to a device under test. As a result, signal transfer speed may be improved and optical resource usage may be reduced.
