A data processing system and a method of operating the same may include a host system and a memory system. The host system may include a host memory and a host controller, and the memory system may include a memory controller and a nonvolatile memory device. The memory controller may include a data attribute determination circuit and a memory selection circuit. The data attribute determination circuit may be configured to determine an attribute of write data received from the host controller. The memory selection circuit may be configured to select, based on the determined attribute of the write data, any one of the host memory and the nonvolatile memory device as a location where the write data is to be stored.

Data processing system and operating method thereof

There are provided a memory system including a semiconductor memory device and a controller and an operating method thereof. A memory system having an extended storage area includes a semiconductor memory device including a plurality of memory blocks, and a controller for controlling the semiconductor memory device. In the memory system, the semiconductor memory device stores system information required to drive the semiconductor memory device and the controller in one memory block among the plurality of memory blocks.

Memory system and operating method thereof

A memory system includes a memory device, to which a first power is supplied, and in which data is stored; a controller, to which s second power is supplied, and which is configured to control the memory device; an interface, to which a third power is supplied, and which is configured to transmit a command and data between the controller and the memory device; and a Low Dropout (LDO) Regulator configured to convert the first power into the third power and supply the third power to the interface.

Memory system

A data storage device includes a nonvolatile memory device including a buffer region and a main region; and a controller suitable for controlling a buffer write operation of the nonvolatile memory device such that write-requested first data is stored in the buffer region, and controlling a main write operation of the nonvolatile memory device such that the first data stored in the buffer region is stored in the main region according to a write mode, wherein the nonvolatile memory device performs the buffer write operation regardless of the write mode.
