Abstract: A memory device and a method of controlling an input signal of the memory device. In the method of controlling an input signal according to test modes, it is determined whether the input signal is in a first test mode or a second test mode. If the memory device is in the first test mode, in response to a control signal, an input signal is received through input pins. In response to a mode signal, the input signal is separated into data and an address. The separated data and address is applied to the core of a memory device. If the memory device is in the second test mode, an input signal is received through input pins and inverting input pins. In response to a mode signal, an address is separated from the input signal received through the input pins and the data is separated from the input signal received through the inverting input pins. The separated data and address are applied to the core of a memory device.

Abstract: A method for reducing channel skew of a test system which has a plurality of channels and which is used for testing a device connected thereto. The method includes performing system calibration, fine adjusting the test system manually, and recording signal characteristics appearing at the channels during the fine adjusting as eye-shmoo data indicating rising or falling characteristics of signals. Thereafter, system calibration on the test system is performed when a predetermined period has elapsed since the recording, and skew between the channels is then adjusted by performing software processing of the test system using the recorded data. Since the device is not installed in the test system during the test, damage of the test system socket pads may be prevented, so that an error in the test system can be reduced. In addition, time for adjusting channel skew can be reduced.
