A controller may be configured to control an operation of a nonvolatile memory and to determine a write command processing schedule by analyzing patterns of commands queued in a command queue during a first unit time, the commands queued in the command queue during the first unit time including a first write command, a first read command, or both and to process a second write command queued in the command queue during a second unit time subsequent to the first unit time, based on the determined write command processing schedule.

Controller, operating method of controller and storage device including the same

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

An operating method of a data storage device including nonvolatile memory devices includes making a victim block list for victim blocks for which a merge operation is to be performed and copying valid pages of the victim bocks to a merge block. The method also includes determining whether there is a victim block which has an erase-held valid page selectively erasing the victim blocks included in the victim block list, according to which victim blocks have an erase-held page, and updating the victim block list according to which victim blocks are erased.

Data storage device for holding erasure of victim block having valid page copied to merge block and method of operating the same

An operating method of a data storage device may include performing a first write operation on a first memory region, and performing a second write operation on a second memory region to store position information on the first write operation.
