A memory controller and a method of operating the same may move data from a first memory buffer to a second memory buffer. The memory controller may include a host controller configured to receive host data corresponding to a program request from a host and to control transmission of the host data so that the host data is programmed to a memory device, a flash controller configured to receive flash data corresponding to a read request from the memory device and control transmission of the flash data to the host, and a memory buffer component including the first memory buffer and the second memory buffer configured to store the host data, flash data, or both. The memory controller is configured to control the memory buffer component so that the host data, flash data, or both are moved from the first memory buffer to the second memory buffer.

Memory controller and method of operating the same

Disclosed is a memory system including a controller configured to authenticate a user who inputs a request for discarding the memory system, to verify whether the request is valid when the user is authenticated as a legitimate user, to register discard activation of the memory system when the request is valid, and to transmit the request to a memory device; and the memory device configured to determine whether the transmitted request is valid, and to register the discard activation of the memory system when the request is valid.

Memory system and memory system discard method

There are provided a storage device and an operating method thereof. The storage device includes: a nonvolatile memory device including a system block for storing firmware data including a program code of firmware, a signature in which the program code is encoded, and an authentication key; a volatile memory device configured to store operational firmware data; and a memory controller configured to, when power is applied to the storage device, store the firmware data as the operational firmware data in the volatile memory device, perform a firmware validity test for detecting whether the operational firmware data and the firmware data matches each other, in response to a test event, and perform a reset operation based on a result of the firmware validity test.

Storage device and operating method thereof

Embodiments of the present disclosure relate to a memory system and an operating method thereof. According to the embodiments of the present disclosure, the memory system may generate a nonce based on a physical address of a target area of a memory device using a cryptographic algorithm, and request the memory device to authenticate the nonce. When the authentication for the nonce succeeds, the memory controller may set an authority to perform a read, write or erase operation on the target area. Through this operation, the memory system can prevent data leakage or damage by a user who has no access authority.

Memory system and operating method thereof

An operating method for a controller includes: receiving a target command; detecting a first command from a first command queue, the first command having a same logical address as the target command; queuing the target command in the first command queue when the first command is not detected from the first command queue; detecting, when the first command queue is full of commands, a second command from a second command queue, the second command having the same logical address as the target command; and queuing the target command in the second command queue, when the second command is not detected from the second command queue.

Controller and operating method thereof

A memory system includes a memory device for storing data; and a memory controller performing a program operation on the memory device by using one of a first program mode and a second program mode. The memory controller counts a number of program operations performed by using the first program mode in which a ratio of dummy data to program data is greater than or equal to a predetermined value; and changes the program mode to the second program mode from the first program mode, when the counted number is greater than or equal to a predetermined number.

Memory controller, memory system having the memory controller, and operating method of the memory controller

A data storage device includes a storage medium; a buffer memory configured to temporarily store data to be inputted to, or outputted from, the storage medium; and a controller configured to control data exchange with the storage medium, allocate a write tag to a write command, and change an attribute of the write tag according to a processing status of the write command.

Data storage device managing write tag, writing operation method thereof, and storage system including the same

A data storage device includes a nonvolatile memory device configured to have a temperature sensor; and a controller, wherein the nonvolatile memory device performs an operation based on an operation command outputted from the controller, and transmits a temperature information measured by the temperature sensor along with an operation result to the controller.
