A data processing system includes a host suitable for generating a plurality of write data grouped into transactions and a plurality of write commands including transaction information of each of the write data; and a memory system suitable for storing the write data in a normal region of a memory device in response to the write commands received from the host, and storing the transaction information included in each of the write commands in a spare region, which corresponds to the normal region, of the memory device.

Data processing system for securing atomicity of transactions without generating separate commit command, and operating method thereof

A memory system includes a non-volatile memory device including a plurality of memory blocks; and a controller comprising a volatile memory and configured to: store a plurality of write data delivered from a host in the memory blocks to the plurality of memory blocks; and managing mapping information corresponding to the stored write data in the volatile memory, wherein the controller is configured to check whether the plurality of write data are grouped into a transaction, selectively set a transaction flag to the mapping information based on a check result; and selectively store the mapping information in the memory blocks when the transaction flag is not set.

Memory system managing mapping information corresponding to write data and operation method thereof

A memory system may include: a memory device including a plurality of memory blocks; and a controller suitable for grouping the memory blocks based on type into a plurality of super blocks according to a preset condition and managing the memory blocks by managing the super blocks, the controller may manage one or more of the super blocks, in each of which at least one bad memory block and good memory blocks are grouped, by classifying the one or more superblocks as first super blocks, and the controller may differently manage uses of the respective first super blocks based on the numbers of bad memory blocks included in the respective first super blocks.
