Abstract: A method for manufacturing a nano wire memory device and a control system for forming a nano wire used are provided to form the nano wire in position and to improve the yield of a memory cell by forming one nano wire between an electrode and a dummy electrode using a CMOS logic. An electrode(40) and a dummy electrode(42) are formed on a substrate. The current between the electrode and the dummy electrode is measured and a nano wire(44) is formed between the electrode and the dummy electrode. When the measure current is the same as a given value, the power source applied between the electrode and the dummy electrode is blocked. The dummy electrode is removed. The nano wire forming process is performed by using a predetermined system composed of a switching logic and a current monitor under composite electric field conditions. A CMOS logic is used as the predetermined system.

Abstract: An HDD(Hard Disk Drive) having a function of sensing a fall as sheltering a head in case of fall impact is provided to previously sense whether a free fall of a device occurs, and to shelter a read/write head taking charge of recording/reproducing of data to a safe parking position, thereby obtaining impact resistance performance required in a mobile environment. A flying height sensor measures height in which a rotating body flies on a spindle motor(100), in real time. A monitor unit monitors the flying height detected from the sensor, and generates a free fall signal if it is decided that an HDD is in the free fall state. A central controller starts to shelter a read/write head(161) by responding to the free fall signal. The flying height sensor is positioned on a base member mounted with the spindle motor, and measures the flying height of the rotating body from the base member to output the measured height as an electric signal.
