Abstract: A memory system includes a memory device including a first and a second group of memory blocks; and a controller suitable for: performing a processing operation corresponding to a plurality of workloads included in transactions received from a host, checking transaction identification information and completion information included in the workloads, storing first workloads among the workloads in the memory blocks included in the first group, corresponding to the identification information and the completion information, and transmitting and storing the first workloads into the memory blocks included in the second group.

Abstract: A data processing system includes a host device including a first volatile memory which includes an exclusive region and a shared region, and a first control unit; and a data storage device including a second control unit, and configured to store data to be accessed by the host device, wherein the first control unit adds a header information including an identification information and a state information, to data to be stored in the data storage device, and stores the data added with the header information, in the shared region, according to a request of the second control unit

Abstract: A data storage device includes a nonvolatile memory device including first and second memory regions; and a controller suitable for performing a pattern identification operation for write requests, based on a pattern information for one or more patterns, and storing data corresponding to the write requests in one of the first and second memory regions according to a result of the pattern identification operation.

Abstract: This technology relates to a memory system in which a plurality of memory devices operates in an interleaving manner and an operating method of the memory system. The memory system may include a plurality of memory devices, a host controller suitable for generating a plurality of internal read commands by splitting an external read command applied from a host in a minimum read size, and a memory controller suitable for checking information about internal read commands which belong to the plurality of internal read commands and which are sequentially late in a section in which a read operation is performed on the plurality of memory devices based on check values of information about internal read commands which belong to the plurality of internal read commands and which are sequentially ahead.
