Abstract:
Disclosed is a storage device which includes a nonvolatile memory device including a memory block a program order of which is adjusted regardless of an arrangement of memory cells, and a memory controller that performs address mapping to replace a bad page of the memory block with a normal page of the memory block.
Abstract:
A substrate attachment system, including a portable chamber for receiving a pair of substrates which are aligned; a conveyor transportation device which continuously moves the portable chamber and to which a vacuum generator that is connected to a vacuum port of the portable chamber to evacuate the inside of the portable chamber is provided; and a heating device for performing a heating process in which the aligned substrates are attached to each other in the portable chamber, wherein the conveyor transportation device is arranged to pass through the heating device. The substrate attachment system may contribute to high attachment accuracy, and also, since the size of a chamber is reduced, a spatial utilization rate may be high, and also, since an attachment process is continuously performed by using a conveyor transportation device, a process time may be reduced.
Abstract:
A liquid crystal display (“LCD”) for eliminating an afterimage includes a power supply, a gate driver and a discharger. The power supply detects the cutting off of external power voltage and supplies a discharge signal. The gate driver simultaneously supplies a gate driving signal to a plurality of gate lines in response to the discharge signal, and the discharger supplies a common voltage to a plurality of data lines in response to the discharge signal.
Abstract:
Disclosed is a method of writing data in a storage device including a nonvolatile memory device. The method includes receiving write data with a write request, detecting a number of free blocks, if the detected number of free blocks is less than a threshold value, allocating a log block only in accordance with a sub-block unit, but if the detected number of free blocks is not less than the threshold value, allocating the log block in accordance with one of the sub-block unit and a physical block unit, wherein the sub-block unit is smaller than the physical block unit.
Abstract:
A memory system, including a flash memory including multiple memory blocks, and a controller configured to erase each of the memory blocks using multiple steps. The controller stores, for each of the memory blocks, metadata indicating which of the multiple steps have been completed, and erases each of the memory blocks based on the stored metadata.

Abstract:
A gas supplying apparatus for supplying deposition gas onto a substrate surface, the gas supplying apparatus comprising: a gas supplying ring with one or more gas supplying channels formed along the interior of the gas supplying ring and with a plurality of gas distribution channels directed toward a center of the gas supplying ring; and a plurality of adapters with gas nozzles connecting to the gas distribution channels, respectively, that detachably connect to the interior of the gas supplying ring, wherein the gas nozzles have a variety of injection configurations.
Abstract:
Disclosed is a variable alignment-type optical fiber block in which alignment of waveguides can be changed according to temperature. The optical fiber block includes: a substrate having a receiving section formed at one end of the substrate, the receiving section having a predetermined volume; a ferrule seated in the receiving section, the ferrule having a hole in which an optical fiber is inserted; a first expandable block disposed between one side surface of the ferrule and an inner wall surface of the receiving section, which are opposed to each other, the first expandable block having a first thermal expansive coefficient; and, a second expandable block disposed between the other side surface of the ferrule and another inner wall surface of the receiving section, which are opposed to each other, the second expandable block having a second thermal expansive coefficient.
