摘要:
A method is provided for operating a data storage device comprising a storage medium and a controller configured to control operations of the storage medium. The method comprises determining whether a read-requested data strip is an error data strip, reading a plurality of data strips in a stripe comprising the read-requested data strip when the read-requested data strip is the error data strip, outputting a data strip recovered using the other data strip except the error data strip among the plurality of data strips, and writing the recovered data strip and the other data strips into the storage medium.

Provided is a flash memory address translation method that may maintain at least one chip that may be divided based on at least one horizontal bank and at least one vertical channel, and may divide the at least one bank by at least one stripe partition, managing an error of a chip without deterioration in a performance of a small writing.

A method is provided for performing a write operation in a data storage device comprising a storage medium, a processing unit, and a buffer memory storing data to be transferred to the storage medium under control of the processing unit. The method comprises aggregating data in the buffer memory as a strip group comprising multiple data strips, transferring data strips in at least one strip group to the storage medium, calculating a parity strip based on the transferred data strips of the at least one strip group without additional access to the buffer memory, and transferring the parity strip to the storage medium.
摘要:
A flash memory and a method of writing data to a flash memory during garbage collection of the flash memory is provided. First, a garbage collection process on a victim block of flash memory may be initiated. A garbage collection process may comprise a plurality of garbage collection operation. A program command and corresponding program data may be received. After a first garbage collection operation has finished and a portion of flash data from the victim block has been written to a free block, a portion of the program data may be written to that free block. If data remains in the victim block, a second garbage collection operation may be performed.
摘要:
A write method of a data storage device including a storage media includes compressing data to be stored in the storage media; determining compressed data start positions of a physical unit of the storage media in which the compressed data is to be stored; and storing the compressed data from the determined compressed data start positions of the physical unit, respectively.

An intuitive real spatial aiming-based system and identification and communication methods are presented. The intuitive real spatial aiming-based system includes aiming device, target devices and an indoor location-based service server. The aiming device includes a mobile computer or a Personal Digital Assistant (PDA), which is provided with a first wireless communication tool, a first location tracking sensor, and an electronic compass having a magneto resistive sensor for detecting a directions. The target devices each includes a fixed computer, a home appliance, a PDA, or a mobile communication terminal, which is selectively provided with second wireless communication tool and a second location tracking sensor. The indoor location-based service server tracks the indoor locations and coordinates the aiming device and the target devices in real time. To tolerate sensor's error, an angle-based target region, a width-based target region, and a combination of the two regions presented.

Disclosed are a backlight unit and a liquid crystal display device having the same. A supporting section is formed with a reflector, which is used for a direct type backlight unit, to support optical sheets and guide light, so that the assembling process is simplified and the manufacturing cost is reduced.
