Electronic device

A method for operating a controller which controls a memory device including a plurality of memory blocks operating in multi-level cell mode or a single level cell mode includes setting some of the plurality of memory blocks operating in the multi-level cell mode, to system memory blocks in response to a power-off request from a host, setting the system memory blocks to the single level cell mode, and controlling the memory device to store system data in the system memory blocks.

Operation method of a controller

A memory system includes: a memory device suitable for storing an encrypted first boot image including first firmware, an encrypted second boot image including second firmware, and a second authentication key for decrypting the encrypted second boot image, and a controller suitable for controlling the memory device and including a boot memory provided with a boot loader and a first authentication key for decrypting the encrypted first boot image, one or more first processing blocks each of which includes a first core, one or more second processing blocks each of which includes a second core, and a buffer memory.

Memory system and operation method thereof

A memory system includes: a memory device comprising a plurality of dies each die comprising a plurality of planes, each plane comprising a plurality of blocks, each block comprising a plurality of pages; a controller suitable for inputting a plurality of commands received from a host to the memory device through command queuing, wherein a first memory die among the plurality of memory dies processes the plurality of commands as a burst command, and performs command operations in one or more pages in one or more first memory blocks included in the first memory die, and data corresponding to the command operations are stored in a plurality of latches corresponding to the one or more first memory blocks.

Memory system using burst command for handling plural commands and operating method thereof

An electronic device is provided which includes a first housing including a first surface and a second surface that faces in a direction opposite or perpendicular to the first surface, a second housing including a third surface that is capable of facing the first surface and a fourth surface that faces in a direction opposite or perpendicular to the third surface, and a hinge structure at least partially inserted into a first recess open on the first surface and a second recess open on the third surface, and couples the first housing and the second housing to be rotatable in relation to each other.

Electronic device including hinge structure

A memory system includes a memory device including a plurality of memory blocks, each memory block including a plurality of word lines, each word line being coupled to a plurality of memory cells, and a controller suitable for grouping the word lines into a plurality of word line groups, wherein when receiving a read command for data stored in a first memory block, the controller performs a read operation for word lines of the first memory block, checks for read fail word lines in the word lines of the first memory block, checks for word line groups including the read fail word lines, and transmits a set command corresponding to the read fail word lines to the word line groups which contain read fail word lines.

Memory system and operating method thereof

Embodiments provide a vertical external cavity surface emitting laser (VECSEL) that may provide a uniform current density in an active layer using a double current injecting channel. The surface emitting laser device may include a double channel current injection structure for uniformly applying current to an active layer, wherein the double channel current injection structure may include: a first current injection channel, which may allow current to be injected toward a central portion of an aperture, which may be a light beam output region formed in the active layer, and may have a smaller diameter than the aperture: and a second current injection channel, which may allow current to be injected toward an edge of the aperture and may be located around the aperture.

Surface emitting laser device having double channeled structure

Provided is a method of fabricating a laser diode including a lower Al-containing semiconductor material layer, a active layer, and an upper Al-containing semiconductor material layer. The method includes thermally cleaning the inside of a deposition reactor in which a substrate on which the lower Al-containing semiconductor material layer is stacked is loaded. During the thermal cleaning process, the inside of the deposition reactor is thermally treated at a predetermined temperature in an atmosphere of a gas mixture of AsHand Hthat is injected into the deposition reactor.

Method of fabricating a laser diode that includes thermally cleaning a deposition reactor using a gas mixture of arsine and hydrogen

A terminal connecting device includes a main body of a terminal block having diaphragms and supporting strips, a terminal plate positioned at the top of the supporting strips, movable terminals supported by a spring to attach or detach lead wire positioned on the terminal plate, a restraining structure, proximate to the movable terminals, which limits the movement of the lead wire, and a terminal screw coupled with the movable terminals after being penetrated through the through hole of the lead wire and fastened at a screw hole of the terminal plate. The restraining structure restricts the lead wire from diverting or dropping, thereby preventing safety accidents such as stopping the operation of facility or electric shock. The restraining structure also allows easy penetration of the terminal screw through the through hole of the lead wire in fixing the lead wire, thereby improving productivity due to ease of fastening the terminal screw. The restraining structure may be extending parts extending from the movable parts or hitching jugs protruding at both lateral surfaces of the main body.
