Provided herein may be a storage device and a method of operating the same. The storage device may include a memory device including a plurality of memory blocks, and a memory controller configured to control the memory device and perform a garbage collection operation of securing free blocks in which data is not stored, based on a sum of a number of invalid data blocks and a number of free blocks, among the plurality of memory blocks, wherein the number of invalid data blocks is determined depending on a size of invalid data stored in the plurality of memory blocks.

Storage device and method of operating the same

A storage device and a method of operating the storage device include various memory devices. The storage device includes a plurality of memory devices each including at least one or more read cache memory blocks and a plurality of main memory blocks; and a memory controller configured to spread and store data stored in an identical memory device, having a read count representing a number of read requests and exceeding a threshold value, among data stored in the plurality of main memory blocks, to the at least one or more read cache memory blocks included in each of the plurality of memory devices.

Storage device and method for operating the same

Disclosed is a memory system including: a semiconductor memory device; and a memory controller suitable for controlling the semiconductor memory device, and receiving a first command for accessing the semiconductor memory device, and a second command of a different type from that of the first command from a host. The memory controller completes preparation to perform an operation corresponding to the first command by performing a first booting operation when power is up, and outputs a first command ready signal to the host. The memory controller completes preparation to perform an operation corresponding to the second command by performing a second booting operation after the first booting operation, and outputs a second command ready signal to the host.

Memory system, computing system including the same and method of operating memory system

A memory system and an operating method thereof stably supplies power, so that it is possible to improve performance of a memory system by omitting an operation, which has been performed in order to prevent an error due to the blocking of a power supply, in a condition in which an error due to the blocking of the power supply may not be generated.

Memory system and operating method thereof

An operating method of a data storage device includes determining whether the data storage device is in a main boot mode or a sub boot mode, based on data stored in a boot mode register; executing a main boot code stored in a ROM, when the data storage device is determined to be in the main boot mode; and executing a sub boot code loaded on a working memory, when the data storage device is determined to be in the sub boot mode, and then, executing the main boot code.

Operating method of data storage device

A data storage device includes: a nonvolatile memory device comprising a plurality of memory blocks, each including a plurality of pages; and a controller suitable for controlling an operation of the nonvolatile memory device in response to a request from an external device, wherein the controller determines whether or not a memory block including damaged pages in which stored data are damaged occurs in the memory blocks, sets a memory block including the damaged pages to an invalid memory block based on the determination result, and regenerates free pages of the memory block set as the invalid memory block into a valid memory block.

Data storage device and operating method thereof

A data storage device includes a nonvolatile memory device; and a controller suitable for controlling an operation of the nonvolatile memory device in response to a request from an external device, wherein the controller comprises a victim block setup unit suitable for setting a victim block for a merge operation based on an error count, which is detected when a read operation of the nonvolatile memory device is performed, and for storing information of the victim block for the merge operation, and wherein the controller converts the victim block into a free memory block during the merge operation and reuses the free memory block to store data.
