A data storage device in accordance with an embodiment may include a controller and a memory device. The controller is configured to output a read control signal including an option number related to a read condition. The memory device is configured to perform a read operation based on a read condition corresponding to the option number in response to the read control signal. The read condition for the option number is configured to be stored in a read condition table storage circuit included in the memory device.

Data storage device with efficient changing read option, and controller, memory device, and operating method thereof

A data storage device may include a storage that store data in a plurality of physical storage spaces to which physical addresses are assigned, respectively, and a controller that control the storage, wherein the controller includes a mapping table of the physical addresses corresponding to logical addresses managed by a host, and wherein the controller is further configured to read data, in a primary read operation, from a physical storage space of a physical address corresponding to a logical address requested to be read by the host among the plurality of physical storage spaces according to the mapping table, obtain a normal physical address corresponding to the logical address requested to be read through the mapping table when the data read in the primary read operation is erased data; and read data, in a secondary read operation, from a physical storage space of the normal physical address.

Data storage device, operation method thereof, and controller therefor

Provided herein may be a storage device and a method of operating the same. A memory controller may include a power application timer configured to measure each of plural final power application times, each final power application time being a period of time during which power is applied to the memory controller until the memory controller is turned off after being turned on, and a command blocker configured to disable a set command, among commands that are input from a host to the memory controller depending on a cumulative power application time obtained by accumulating the plural final power application times.

Storage device for security access and method of operating the same

A data storage device includes a nonvolatile memory device including a plurality of memory blocks; a random-access memory including a bad block management module configured to register and manage bad blocks included in the plurality of memory blocks; and a processor configured to detect primary bad blocks by performing a primary bad block scan operation on the plurality of memory blocks using the bad block management module, detect secondary bad blocks by performing a secondary bad block scan operation on normal memory blocks other than the primary bad blocks among the plurality of memory blocks, and register the detected primary bad blocks and the detected secondary bad blocks as bad blocks.
