Abstract:
The present invention relates to a method for photographing a radiography image using an apparatus for photographing a radiography image. According to an embodiment of the present invention, the method for photographing a radiography image includes a step of displaying the parameter value of an apparatus for photographing a radiography image with regard to the preset part of an object and a preview image corresponding to the parameter value; a step of changing the parameter value or the preview image based on the input of a user; and a step of changing the parameter value according to the changed preview image or changing the preview image according to the changed parameter value.
Abstract:
PURPOSE: A semiconductor memory device including an on-die termination, a memory controller, a memory system, and a method for controlling the on-die termination are provided to improve the fidelity of a signal by preventing the change of an ODT(on-die termination) equivalent resistance in an operation state combination of different chips and confliction due to the skew of the ODT control timing. CONSTITUTION: A first memory chip(1210) includes a first pad to receive a first signal and a first ODT unit(1213) which is electrically connected to the first pad. The first pad is connected to a first terminal of the semiconductor memory device. A second memory chip(1220) includes a second pad to receive the first signal and a second ODT unit(1223) which is electrically connected to the second pad. The second pad is connected to the first terminal of the semiconductor memory device. One of the first ODT unit and the second ODT unit is on or off according to a memory operation and the other is off regardless of the memory operation. The ODT unit which is on or off is changed to the first ODT unit or the second ODT unit.

PURPOSE: A semiconductor chip open test circuit and a semiconductor chip test system including the same are provided to accurately determine the open state of a semiconductor chip electrode by connecting a negative voltage line inputted with a negative voltage, which is lower than a ground voltage, to a protective diode. CONSTITUTION: A test node(210) is short circuited with an electrode of a semiconductor chip connected between a first protection diode connected to a source voltage line and a second protection diode connected to a grounded voltage line. A current source(240) applies a negative current to the test node. An ESD(Electric Static Discharge) protection part(220) comprises a third protection diode connected to the source voltage line and a fourth protection diode connected to the negative voltage line.
