A memory system which includes a flash memory including a meta block and a data block, and a memory controller including a meta data managing module managing meta data to be stored in the meta block. The meta block includes a plurality of pages. The meta data managing module compares a number of free pages of the plurality of pages with a preset number of free pages, and selects a write target page of the meta data by using one of a consecution meta write operation or a dirty meta write operation, depending on a result of the comparison.

Memory system based on flash memory and method for managing meta data thereof

A storage system is disclosed and related methods of reading/writing data are disclosed. The storage system includes a main data storage medium, and first and second buffers storing data to be stored on the main data storage medium, as well as a controller defining a data I/O path. The data I/O path may be defined in relation to a detected operating state of the main data storage medium.

Storage system, related data processing apparatus, and I/O method

A method is for recovering a block mapping table in a system including a flash memory device, where the block mapping table utilizes address mapping in accordance with a wear-leveling scheme. The method includes reading block arrangement information from the flash memory device for the wear-leveling scheme, restoring the block mapping table with reference to allocation block information included in the block arrangement information and scanning address allocation information included in spare regions of erased blocks of the flash memory device with reference to erased block information included in the block arrangement information and updating the block mapping table in accordance with the scanned address allocation information.

System with flash memory device and data recovery method thereof

Example embodiments provide a garbage collection method which includes applying a weight to each of at least two or more factors to calculate garbage collection costs. A hash table is configured using the calculated garbage collection costs. The method further includes searching a block having the lowest garbage collection cost from the hash table and performing garbage collection on the searched block.

Flash memory system and garbage collection method thereof

A hard disk drive is disclosed and related methods of reading/writing data are disclosed. The hard disk drive includes a disk serving as a main data storage medium, and first and second buffers storing data to be stored on the disk, as well as a controller defining a data I/O path in relation to a detected operating state of the hard disk drive.

Hard disk drive with reduced power consumption, related data processing apparatus, and I/O method

A system and method for extracting a corner point in a space using pixel information obtained from a camera are provided. The corner point extracting system includes a light generation module emitting light in a predetermined form (such as a plane form), an image acquisition module acquiring an image of a reflector reflecting the light emitted from the light generation module, and a control module obtaining distance data between the light generation module and the reflector using the acquired image and extracting a corner point by performing split-merge using a threshold proportional to the distance data. The threshold is a value proportional to the distance data which corresponds to pixel information of the image acquisition module.
