Abstract: A method of controlling a memory system that comprises a first flash memory device and a memory controller, the method comprising counting a first timeout when a sudden power off occurs, resetting the first flash memory device when the first timeout expires, and dumping data to the first flash memory device.

Abstract: Memory blocks of a nonvolatile memory device are managed by identifying a full memory block, determining whether a block life of the full memory block exceeds a threshold value, and upon determining that the block life of the full memory block exceeds the threshold value, selecting the full memory block as a target block for garbage collection. The threshold of the block life is determined using an average write distance of logical pages programmed in the nonvolatile memory device.

Abstract: A method for managing data in a storage device includes: receiving a logical page from a host and calculating an actual time stamp of the logical page; finding a block of the storage device in which the logical page is stored and detecting a time stamp of the block and a page offset of the logical page stored in the block; calculating an approximate time stamp of the logical page stored in the block using the time stamp of the block and the page offset; and determining that the logical page is in a first state if the difference between the actual time stamp and the approximate time stamp is smaller than a threshold value, and determining that the logical page is in a second state different from the first state if the difference between the actual time stamp and the approximate time stamp is larger than the threshold value.

Abstract: A method of managing memory blocks in a nonvolatile memory device comprises identifying a full memory block among a plurality of memory blocks in the nonvolatile memory device, determining whether a block life of the full memory block exceeds a threshold value, and upon determining that the block life of the full memory block exceeds the threshold value, selecting the full memory block as a target block for garbage collection.
