A storage device includes a memory device, and a memory controller configured to receive data and a log related to a property of the data from an external host, allocate a super block in which the data in the memory device is to be stored and a physical zone in the super block based on the log of the data, and store information for the log of the data stored for each physical zone and a time point at which a physical zone of a full state in which an empty area does not exist is switched to the full state. The memory controller controls the memory device to perform garbage collection according to the number of physical zones of an empty state, and selects a victim physical zone based on the information for the log of the data and a full state switch time point.

Storage device and method of operating the same

The present technology includes a storage device including a memory device including a first storage region and a second storage region and a memory controller configured to, in response to a write request in the first storage region from an external host, acquire data stored the first region based on a fail prediction information provided from the memory device and to perform a write operation corresponding to the write request, wherein the first storage region and the second storage region are allocated according to logical addresses of data to be stored in by requests of the external host.

The present technology includes a memory controller that allocates a new buffer memory area in a buffer memory or stores temporarily stored data in the buffer memory into a memory device based on a state of an auxiliary power device that supplies power to the memory device and the memory controller, and a power state of a host.

Memory controller based on flush operation and method of operating the same

A storage device includes a memory device including a plurality of sequential areas and a random area other than the plurality of sequential areas, the plurality of sequential areas storing pieces of data corresponding to consecutive logical addresses input from a host, a buffer memory device configured to temporarily store write data corresponding to a write request provided from the host and an operation controller configured to generate combined data by adding dummy data to the write data having a size less than a program unit size of the memory device, a size of the dummy data corresponding to a difference between the size of the write data and the program unit size, store the combined data in the memory device, and store combined data information, relating to the combined data stored in the memory device, in the buffer memory device.

A system includes an application processor configured to generate a read request and including a data memory; a host processor configured to generate a read command corresponding to the read request; and a data storage device including a data storage memory, wherein the data storage device transmits read data output from the data storage device according to the read command to the data memory of the application processor without passing the host processor.

System including an application processor and a data storage device providing data

A memory system includes a storage medium having a plurality of memory regions. A controller is configured to allocate each of a plurality of open memory regions among the memory regions to one or more levels and store, in response to a write request received from a host device that includes data and a level of the data, the data in an open memory region allocated to the level. A level may be a level of a file in a predetermined unit in which the data is included, such as in a log-structured merge (LSM) tree structure.

Memory system for storing data of log-structured merge tree structure and data processing system including the same

A storage device includes a memory device including a plurality of memory areas respectively corresponding to a plurality of address groups each of which includes consecutive logical addresses provided by a host, a buffer memory including a common buffer and a plurality of zone buffers, the plurality of zone buffers respectively corresponding to the plurality of memory areas, and a memory controller for controlling the buffer memory to temporarily store write data corresponding to a logical address provided from the host in one of a zone buffer corresponding to the logical address and the common buffer according to whether a first size of the write data exceeds an available storage capacity of the zone buffer, the available storage capacity representing a size of an empty storage space of the zone buffer in which no data is stored.

Storage device including a buffer memory having a common buffer for storing over-sized write data, and operating method thereof

Memory controller and method of operating the same

A data storage apparatus includes a volatile memory, the volatile memory including a region in which a zone mapping table and system information are stored and a random access zone capable of random write. The data storage apparatus further includes a non-volatile memory including a backup zone and a plurality of sequential zones capable of sequential write, and a controller configured to identify whether a logical address belongs to the random access zone or the sequential zone when the logical address and a data size are received along with a write command or read command from a host apparatus and to control an operation corresponding to the write command or read command.
