A storage device may receive, from an external device, a target read recovery level indicating information on a read command execution completion time and an error recovery amount requested by the external device, may read, from a memory, data requested by a read command transmitted by the external device, and may transmit, to the external device, a response regarding a result of executing the read command transmitted by the external device within the read command execution completion time indicated by the target read recovery level.

System and storage device for executing read command using read recovery level and methods of operation

The present technology includes a storage device including a memory device including a first storage region and a second storage region and a memory controller configured to, in response to a write request in the first storage region from an external host, acquire data stored the first region based on a fail prediction information provided from the memory device and to perform a write operation corresponding to the write request, wherein the first storage region and the second storage region are allocated according to logical addresses of data to be stored in by requests of the external host.

Storage device and method of operating the same

A storage device having improved data recovery performance includes a memory device including a first storage region and a second storage region, and a memory controller that controls the memory device. Before performing a write operation in the first storage region, the memory controller may backup data previously stored in the first storage region, based on a fail probability of the write operation to be performed in the first storage region. If the write operation fails, the previously-stored data may be recovered from where it was backed up.

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

Provided herein may be a memory controller and a method of operating the same. The memory controller may control a memory device in response to a command received from a host. The memory controller may include a write amplification factor (WAF) storage and a standby state controller. The WAF storage may store a WAF of the memory device. The standby state controller may control entry of the memory controller into a standby state based on a value of the WAF stored in the WAF storage.

Memory controller and method of operating the same

A data storage device includes a data storage medium; a micro control unit (MCU) connected to a host through a first interface method and configured to control the data storage medium in response to a request of the host; and a buffer memory connected to the host through a second interface method, connected to the MCU, and controlled by the MCU and the host, respectively.
