A semiconductor device includes a nonvolatile memory storing encrypted management data, and a memory controller coupled between the nonvolatile memory and a host. The memory controller is allocated a free area in a host memory from the host and is suitable for storing the encrypted management data in the free area.

Memory controller communicating with host, operating method thereof, and computing system including the same

A data storage device that includes a nonvolatile memory device, a controller suitable for controlling the nonvolatile memory device and for reading and writing data to the nonvolatile memory device, and a power management unit suitable for supplying power to the nonvolatile memory device. The controller may control the power management unit to adjust the power supplied to the nonvolatile memory device.

Data storage device capable of reducing power consumption

Provided are a semiconductor memory device, a memory system including the same, and an operating method thereof. The semiconductor memory device includes a memory cell array including a plurality of memory cells, a peripheral circuit suitable for reading least significant bit data and most significant bit data of neighboring memory cells adjacent to selected memory cells out of the plurality of memory cells, and generating pattern flag data using the least significant bit data and the most significant bit data and a control logic suitable for controlling the peripheral circuit to set a read voltage to be applied to the selected memory cells based on the pattern flag data.

Semiconductor memory device, memory system including the same and operating method thereof

A memory system and an operating method thereof are provided. The memory system includes a semiconductor memory device configured to perform a read operation and a controller configured to control the read operation of the semiconductor memory device, and the controller, by determining programmed states of memory cells located nearby selected memory cells, divides the selected memory cells into a plurality of groups depending on an amount of interference, and corrects data of one of the groups having a great amount of interference.
