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

According to an embodiment of the present technology, an electronic device may include a host device including: an application requesting to write data; and a file system configured to generate, in response to the request of the application, a log regarding a property of data, and allocate a section corresponding to the data based on the log; and a storage device comprising: a memory device including a plurality of memory dies; and a memory controller configured to control the memory device to receive the data and the log of the data from the host device, and sequentially store the data in a physical zone corresponding to the section.

Host device, storage device, and electronic device

A storage device may include a memory device including a plurality of memory dies; and a memory controller configured to control the memory device in units of super blocks each including two or more memory blocks included in the memory device, wherein at least one of the super blocks within the memory device is a super block including a plurality of small multi-die zones each including a portion of each of the memory blocks included in different memory dies among the memory dies, wherein the memory controller is further configured to receive a garbage collection request and information on valid pages included in the small multi-die zone, and to select, among the super blocks within the memory device, a victim super block in response to the garbage collection request and information on valid pages included in the small multi-die zone.

Method and system for garbage collection

The present technology relates to an electronic device. According to the present technology, a computing system may include a storage device and a host. The storage device may include a plurality of zones. The host may receive storage area information including an optimal write size of an open zone among the plurality of zones from the storage device, determine a target size of data to be flushed to the storage device based on the optimal write size, a history size that is a size of data previously flushed to the storage device, and a buffer data of the host, and flush data having the target size among the buffer data to the storage device.

Computing system for optimal write 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 memory system includes a plurality of memory devices and a controller, wherein each of the plurality of memory devices includes zone blocks. The controller is configured to evenly distribute open zone blocks within the memory devices by referring to an activated zone block count table and a full zone block count table. The activated zone block count table includes an activated zone block count of each of the memory devices, and the full zone block count table includes a full zone block count of each of the memory devices.

Memory system and operating method thereof

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.
