A method of operating a host includes defining transaction identifications for each one of multiple transactions in a multi-transaction, thereafter communicating atomic write data related to each transaction to a data storage device using the transaction ID, and storing the atomic write data in the data storage device using the transaction ID and an identifier.

Atomic write method for multi-transaction

A host receives information related to garbage collection of a storage device, and the host controls selective execution of garbage collection by the storage device according to the received information.

Host-driven garbage collection

A storage device performs in-storage computing operation, and includes a non-volatile memory configured to store data and a controller. The controller may include an on-chip memory and may control an operation of the non-volatile memory. The controller receives a data processing code generated by a host, overlays the data processing code on the on-chip memory, processes first data corresponding to the data processing code among the data stored in the non-volatile memory, and transmits the processed first data to the host.

A host generates an address array including a header and each start address to perform a data processing operation, which may for example be 4 Kbytes of a random read operation or a random write operation, and transmits a generated address array to a data storage device through a data bus. The data storage device, in the case of a random read operation, outputs each data corresponding to the each start address to the host successively by using the address array. In the case of a random write operation, the data storage device receives each data corresponding to each start address from the host and stores it in a memory core.

Method of processing data and system using the same

A method is for adaptively adjusting a user storage region in an entire storage region of a nonvolatile memory system. The method includes a host transmitting a user region information request command to the nonvolatile memory system, the nonvolatile memory system transmitting user region information to the host, the host changing the user region information, the host transmitting a user region information setting command to the nonvolatile memory system, and the nonvolatile memory system controlling a size of the user storage region in response to the user region information setting command.

A host receives information related to garbage collection of a storage device, and it controls selective execution of garbage collection by the storage device according to the received information.

Provided is a flash memory system supporting flash defragmentation. The flash memory system includes a host and a flash storage device. In response to a flash defragmentation command by the host, the flash storage device performs flash defragmentation by grouping fragments stored in fragmented blocks of a flash memory on a flash memory management unit basis. The flash memory management unit may be a memory block or page. The flash storage device performs the flash defragmentation regardless of the arrangement order of fragmented files stored in the flash memory.
