    Abstract: A computing system includes a host and a storage device. The host includes a central processing unit (CPU) and a first volatile memory device. The storage device includes a second volatile memory device and a nonvolatile memory device. The CPU uses the first volatile memory device and the second volatile memory device as a main memory to store temporary data used for operation of the CPU. The CPU determines a swap-out page to be swapped-out of first pages stored in the first volatile memory device, determines a swap-in page to be swapped-in of second pages stored in the second volatile memory device, and exchanges the swapped-out page and the swapped-in page.

    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 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.

    Abstract: 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.
