A storage device including: a memory device including a plurality of superblocks, wherein each superblock includes memory blocks included in a group of a plurality of non-volatile memories; and a controller for controlling the memory device, wherein the controller controls a first superblock among the plurality of superblocks to be erased to program data received from a host, controls the data to be programmed in the first superblock, controls the first superblock to be selected as a victim superblock for a garbage collection operation, and controls a media scanning operation to be performed on the memory device when a data duration is greater than a threshold, wherein the data duration is an interval between a first time point, at which the first superblock is erased, and a second time point, at which the first superblock is selected as the victim superblock.

Storage device

A storage device and operating method thereof includes a storage controller configured to receive a get log page command from a host and transmit, to the host, log data about at least one context selected from among respective contexts of a plurality of components according to the get log page command, and a memory storing the log data, wherein the get log page command includes selection information for selecting at least one component from among the plurality of components.

Storage device and operating method thereof including storing log data

A storage device includes a communication circuit and a controller. The controller is configured to transmit log data to a host device through the communication circuit in response to receiving a first signal from the host device, receive a second signal, including an operation condition of an algorithm of the storage device, from the host device through the communication circuit, and change the operation condition of the algorithm on the basis of the second signal, wherein the algorithm includes one or more instructions for controlling an operation of the storage device.

Storage device and operating method thereof

A storage device and an operating method thereof are provided. The storage device includes a memory configured to store parameter data used as an input in a neural network. The storage device also includes a storage controller configured to receive a request signal from a host. The storage controller is also configured to encode, based on the parameter data, log data in the neural network, the log data indicating contexts of the plurality of components, and transmit the encoded log data to the host.

Provided are a memory controller, a method of operating the memory controller, and a storage device including the memory controller. The method includes performing a first operation on a non-volatile memory; storing a first code path corresponding to pieces of codes executed as the first operation is performed in a history buffer; comparing the first code path with a plurality of reference code paths related to the first operation; and identifying whether the first operation is abnormally performed based on a result of the comparison.
