A storage device may include: a memory device; a cache memory device including a first cache memory which caches first data among data stored in the plurality of pages and a second cache memory which caches second data among the data stored in the plurality of pages; and a memory controller for counting a number of times that each of the plurality of pages is read and a number of times that each of the plurality of pages is written, based on a read request or a write request which are received from a host, and, moving the first data from the first cache memory to the second cache memory when the first data is stored in a first page and a number of times that the first page is read and a number of times that the first page is written satisfy a predetermined condition.

Storage device managing a multi-tier cache memory and operating method thereof

The present technology relates to an electronic device. More specifically, the present technology relates to a storage system. A storage system according to an embodiment includes a storage tier including a plurality of storage devices, a cache tier allocated for each of a plurality of storage devices and including a plurality of zone groups each including a hot data zone, a warm data zone, and a cold data zone, a system controller that moves data stored in a source storage device to a target storage device through the cache tier.

Storage system and operating method for moving data between storage devices thereof

A data storage device may include a first memory apparatus including a plurality of data blocks having data classified in units of data blocks; a second memory apparatus in communication with the first memory apparatus to store data cached from the first memory apparatus; and a controller in communication with the first memory apparatus and the second memory apparatus. The controller is configured to perform a caching group based caching operation by controlling the first memory apparatus to cache data from the first memory apparatus to the second memory apparatus on a caching group basis. Each caching group includes a first data block requested for caching and one or more other data blocks having the same write count as a write count of the first data block.

Data storage device employing caching groups defined by write counts of data blocks and operating method thereof

A memory system includes: a first cache; a second cache; and a control unit configured to access the first cache as a first level cache in a first cache mode of operation of the memory system and access the second cache as the first level cache in a second cache mode of operation of the memory system.

Memory system

A data storage device includes: a first level memory including a first zone and a second zone, a size ratio of the first zone to the second zone being dynamically adjusted; a second level memory including a third zone and a fourth zone, a size ratio of the third zone to the fourth zone being dynamically adjusted according to the size ratio of the first zone to the second zone; and a controller configured to control data movement among the first to fourth zones, compare a counting value obtained based on the data movement with a reference value, and dynamically adjust the size ratio of the first zone to the second zone and the size ratio of the third zone to the fourth zone according to a result of comparing.

Data storage device and operating method thereof where zones, in first level memory and second level memory, are dynamically adjusted based on data movement between the zones

A vehicular navigation apparatus may include: an input unit configured to receive an image; a display unit configured to display at least one of a navigation image and an input image; and a controller configured to receive the image from the input unit and to control operation of the display unit. Upon receiving the image from the input unit, the controller may be configured to extract a resolution of the input image and to determine whether the resolution of the input image is less than or equal to a reference resolution, and when the resolution of the input image is less than or equal to the reference resolution, the controller may be configured to control the operation of the display unit so as to simultaneously display the navigation image and the input image.

Vehicular navigation apparatus, method of displaying image thereof, and vehicle including vehicular navigation apparatus
