A storage device includes a memory device storing data, and a controller controlling the memory device. The controller obtains and stores a certificate including a public key of an administrator from a host device, provides a nonce to the host device in response to a request from the host device, receives a token request signature including the nonce, a user identifier (ID), an allowed command list and a lifetime from the host device, and when it is verified that the token request signature is generated by a legitimate administrator by decrypting the token request signature with the public key, generates a token for allowing a user corresponding to the user ID to execute a command included in the allowed command list during the lifetime, and a token secret key corresponding to the token, and provides the token and the token secret key to the host device.

Storage controller and method of operating electronic system

A storage device includes a memory device including user memory blocks providing a user data region; and a controller configured to: map logical addresses used in a host to a portion of the user data region, and use a remaining portion of the user data region as an over-provisioning region, wherein the controller is further configured to control the memory device to: erase the user memory blocks based on a sanitize command from the host, provide, to the host, block address information of the user memory blocks based on a block address request from the host, access the user memory blocks based on block state check requests from the host, and provide, to the host, state information indicating whether the user memory blocks are erased according to access results.

Storage device and operation method of electronic system

A magneto resistive random access memory (MRAM) device including a spin orbit torque structure including a stack of an oxide layer pattern, a ferromagnetic pattern, and a non-magnetic pattern; and a magnetic tunnel junction (MTJ) structure on the spin orbit torque structure, the MTJ structure including a stack of a free layer pattern, a tunnel barrier pattern, and a pinned layer pattern, wherein the spin orbit torque structure extends in a first direction parallel to an upper surface of the spin orbit torque structure, the ferromagnetic pattern includes a horizontal magnetic material, and the free layer pattern has a magnetization direction in a vertical direction perpendicular to the upper surface of the spin orbit torque structure, the magnetization direction being changeable in response to spin currents generated in the spin orbit torque structure.

Magnetoresistive random access memory device

Television set assembly

According to certain embodiments, an electronic device comprises: a housing surrounding at least a side surface of the electronic device; a flexible display exposed through a first surface of the electronic device facing a first direction, the exposed area varying based on the movement of the housing; and a flexible material exposed through a second surface of the electronic device facing a second direction opposite to the first direction, the exposed area varying based on the movement of the housing, wherein the width of the flexible material that is exposed through the second surface, expands in a third direction in accordance with the expansion of the width of the flexible display in the third direction, the third direction being substantially perpendicular to the first direction and the second direction.

Dual slidable electronic device

A communication method and apparatus for communicating with an intelligent base station in a wireless communication system are provided. An operation method of the intelligent base station includes determining whether reconfiguration of an intelligent base station group that supports a terminal is necessary, according to movement information of the terminal, the determination being performed by a first intelligent base station included in the intelligent base station group, when the first intelligent base station determines that reconfiguration of the intelligent base station group is necessary, transmitting a join request to join the intelligent base station group, to a nearby intelligent base station not included in the intelligent base station group, receiving a join approval message in response to the transmitted join request, and reconfiguring the intelligent base station group, based on the received join approval message.

Base station group reconfiguration messaging based on terminal movement

An electronic device is provided. The electronic device includes a housing including a first body and a second body, a flexible display disposed such that at least a portion of the flexible display is exposed through a first surface of the housing, a multi-link cover connected to the first body and the second body, and including a plurality of joint parts pivotably coupled to each other, and at least one hinge structure, at least a portion of which is located in an interior of the multi-link cover and foldably connecting the first body and the second body. The multi-link cover has a height that is substantially the same as heights of the first body and the second body and the plurality of joint parts are connected to each other by shafts disposed to cross each other.
